Munich - Despite the presence of a host of world-class players on the pitch, for Jens Lehmann one of the most intriguing battles in Der Klassiker between FC Bayern München and Borussia Dortmund took place on the sidelines.

The former BVB and Germany goalkeeper took to the mic to co-commentate on the game in front of millions of viewers in 207 countries worldwide, keeping a keen eye on the clash between two of the most innovative coaches in football, Pep Guardiola and Thomas Tuchel, and their modus operandi.

“The possession football Bayern play forces the opponents to drop deeper and deeper and deeper. The opponents tire out running after the ball all game and they make a positional error. And Bayern are so good at waiting for those chances to score," said the 45-year-old before kick-off.

The Lehmann in-match analysis

1st minute

"The way Dortmund started the game is very interesting to say the least. They only have four attacking players and moved have Lukasz Piszczek over to left-back. Tuchel had the idea of putting Sokratis Papastathopoulos up against Costa, as the Greek is a very tough opponent."

Dortmund though started adventurously, forcing two early corners and a free-kick in a dangerous position.

4th minute:

"I expect Tuchel to sit a bit deeper and wait to catch Bayern on the counter. BVB have started fairly high up though and the key will be Pierre-Emerick Aubameyang’s position. Dortmund have played long balls up to him and that won them the early free-kick. The problem is that he is too deep on the edge of the area and has no room to exploit his pace."

"Dortmund are still good at pressing in their opponents half to try and force an early goal, but against Bayern that is not an easy tactic to play as their players are all so gifted on the ball."

8th minute:

"It is clear that Bayern have a lot of respect for Dortmund in the opening stages as Julian Weigl is allowed time and space on the ball in the middle of the park as the Bayern defenders were dropping off. That’s something you don’t see too often, especially at home. And Guardiola is already intervening to try and push his players further up as he sniffed the threat."

Even at this early stage, both coaches were on the edge of their coaching zones, directing play almost like a 12th man on the pitch.

18th minute

"Guardiola has changed his set up already and switched to three at the back. That’s why all of a sudden they have started to push further up and squeeze Borussia Dortmund high up the pitch."

20th minute

"Tuchel still hasn’t reacted to Guardiola’s change. Perhaps he hasn’t spotted it, however, as you can’t always spot it immediately when you are at pitch level. And you see the change has had an immediate effect, Borussia Dortmund can’t play the ball out of defence as easily."

22nd minute

"As ever, Dortmund have a very compact formation making it difficult for Bayern to play through the lines. But I think we’ll now see a period of dominance from Bayern because Dortmund are playing with two central defenders against just one striker and that will give them a man extra everywhere else on the pitch."

That certainly proved true as Bayern took the lead in the 25th minute. Jerome Boateng’s long through ball found Thomas Müller in space between the defence. The goal caused holes to appear in the Dortmund formation as they were forced to react to the deficit.

31st minute

"You can see the big gap now between the three forward players and the rest of Dortmund’s midfield. This means they won’t be able to pressurise Bayern as they are afraid of over committing themselves."

Bayern were able to exploit the gap and win a penalty on the counter-attack. Thomas Müller converted and put the home side 2-0 up.However, Dortmund responded immediately with a goal on the break through Aubameyang.

36th minute

"The crucial pass came from Mats Hummels. The cutting diagonal ball to Henrikh Mkhitaryan. One-touch football. Dortmund now need to manage to get forward better than they have been doing."

There was little opportunity to do so, however, as Bayern pressed hard and high.

39th minute

"Guardiola has changed the formation once again. They’re playing 4-4-1-1. He seems to be very wary as Dortmund are getting more of chance to control the midfield. Bayern will wait for the counter-attack now."

45th minute

"You see the benefit of Phillip Lahm’s ability on the ball. He doesn’t just clear it, he keeps possession, looks for a solution and that has now set up another Bayern attack."

That counter may have proved futile, but right at the start of the second-half, Bayern delivered a killer blow with the third just 22 seconds after the restart with a carbon copy of the opener.

46th minute

"Once again, they key was the surprise long ball that nobody was expecting. But Bürki’s starting position was much too deep."

48th minute

"Now we’ll see if Thomas Tuchel will be brave enough to loosen his defence a bit and try and get a better result. It will be difficult for them to win but he may go for a draw, playing two or three at the back and trying to dominate midfield."

50th minute

"The Bayern goals came from a tactic that Borussia Dortmund should have been using. The long balls from the back for Aubameyang to use his pace and go and burst through. But his starting position has been too deep in the Bayern half and it’s Lewandowski and Müller who have used the tactic."

Thomas Tuchel tried to shake things up with a double substitution. Marco Reus and Adnan Januzai entered the fray.

53rd minute.

"And Bayern have reverted once more to a back-four. And we can see once again their fantastic positional game. As long as the opponents don’t come out and play three at the back, they will always outnumber them in midfield. It’s hard for Dortmund to get the ball and Tuchel needs to be brave and change the shape if he wants to get something out of it. If not, they will concede more."

Just three minutes later, that is exactly what happened. Dortmund were caught cold on the break and Götze’s first time cross was slotted home by Lewandowski.

61st minute

"Opponents in the Bundesliga tend to be a bit scared of Bayern, they never change their shape even when they go behind."

Bayern weren’t finished there though as Götze made it five soon after.

66th minute

"It’s masters against apprentices. Experience versus inexperience. And it seems as though Dortmund have given up. They might get a consolation but I don’t expect them to. On a tactical basis, there won’t be a different approach to what they’ve done so far."

69th minute

"Gündogan has battled hard but you suspect that some of the Dortmund players are not yet ready for this big stage. They can gather good experience today, players like Bürki and Weigl. And Reus too needs a secure place in the team to perform at the highest level. That is the difference to Bayern. They have so much experience, their positional play is fantastic and they have the desire to dominate."

73rd minute

"Jürgen Klopp always managed to get some great results at the Allianz Arena and now that is the job facing Thomas Tuchel. He has to find solutions to be competitive here. Unfortunately he has lost the battle of the tacticians by a mile today."

Tuchel had taken a gamble by reshuffling his defence. Sven Bender started at centre-back for the first time in almost two years. Lukasz Piszczeck played at left-back for the first time in his Bundesliga career.

85th minute

"There can’t be too many excuses when you lose 5-1. Dortmund started quite well but then during the course of the game there were too many positional mistakes. You can’t really say that was a successful experiment."

"At the beginning of the game, Dortmund were playing down the flanks but now they are just trying to go through the congested middle, which is not really helpful."

In the end, there was no further action as Bayern switched to cruise control and sealed the 5-1 victory.

"The killer for Borussia Dortmund was the early goal after half-time. They didn’t recover from that. They showed some good moves in the first half after going 2-0 down. They were a bit scared to open up their defensive line because you know when Bayern get their positional game going it is always a threat. It was a learning day for Dortmund. Their players will get another chance to play at such a high level."

"Bayern dominated sometimes through the individual brilliance of their players but through their positional and tactical set-up."
