Atletico vs Bayern
Gladbach vs Barcelona
🔵🔴 XI Barça:— FC Barcelona (@FCBarcelona_es) September 28, 2016
Regulars at Europe's top table
Bayern and Atletico are certainly used to the big occasions...
Chicharito gearing up for Dortmund
Chicharito's 100th goal in Europe apparently didn't go unnoticed last night. The Mexican will be hoping to continue his fine scoring run in Saturday's clash with BVB - and you can read all about it here.
Attack wins you games, defence wins you titles
Atletico with a warning for anybody expecting a goalfest at Vicente Calderon tonight...
Barca prepare to enter the Gladbach Fortress
The Catalans certainly won't have it all their own way at BORUSSIA-PARK, where Gladbach have won eleven games on the bounce!
Goal of the Week

Lahm wants all three points at Vicente Calderon
Bayern captain Philipp Lahm knows how important it is for the Bavarians to build on their Matchday 1 thrashing of FC Rostov.
Fancy seeing you again
Carlo Ancelotti and Diego Simeone have crossed swords as both players and coaches - the Italian notably guiding Real Madrid to 'La Decima' against Simeone's Atletico in 2014 - but they had warm words for each other ahead of tonight's game...
The most important goal in Bayern's history
While Gladbach and Barcelona will face off for the very first time tonight, it's round three for Bayern and Atletico. In May, Atletico sealed an away goals victory over the Bavarians to deny them a place in the Champions League final. But their first meeting, back in 1974, has gone down in Bayern folklore. With 20 seconds of extra time left in the European Cup final, centre-back Hans-Georg Schwarzenbeck tried his luck from 30 yards out. The ball ended up in the back of the net, rescuing a 1-1 draw for Bayern and forcing a replay. Two days later, they romped to a 4-0 win, with Uli Hoeneß and Gerd Müller scoring two goals each. It was the club's first European crown, and they went on to defend it in 1975 and 1976. Meanwhile, just months after that Atletico win, Bayern captain Franz Beckenbauer led Germany to the 1974 World Cup title. And that's why Schwarzenbeck's last-gasp equaliser is widely considered the most important goal in Bayern's history.
The toughest examination yet for Ancelotti's Bayern?
Spanish wisdom: "Playing Atletico is like seeing the dentist. You know it's going to hurt."
Barca draw first blood
Gladbach have lost their second outing in the UEFA Youth League - the U19 equivalent of the Champions League - going down 3-1 to Barcelona. The best run by a German club in the competition came back in 2013/14, when FC Schalke 04 reached the semi-finals.
Guerreiro going from strength to strength
While Andre Schürrle grabbed most of the headlines after his superb equaliser for Dortmund against Real, Raphael Guerreiro played just as big a part in neutralising the reigning European champions. Making only his eighth appearance for BVB, the Portuguese international put in a man-of-the-match performance on the left wing. You can read about his lightning start in Black-and-Yellow here.
Maybe don't ask for hair tips
The 'M' element of Barca's formidable 'MSN' trident may be missing tonight, but 'S' and 'N' are sure to keep the Gladbach defence busy. And the fans, apparently...
Meanwhile, in Madrid...
100 not out for Chicharito, but disappointment for Leverkusen
Chicharito followed up on last weekend's hat-trick heroics by scoring his 100th goal in European club football against Monaco, but it was a frustrating night for Bayer, who conceded an injury-time equaliser and had to settle for a point in Group E. Read the match report here.
Schürrle: "We have a fantastic mentality."
The German international’s thunderous strike last night kept Dortmund’s unbeaten home record against Real Madrid intact, even if they missed out on a fourth straight victory. Here’s what the BVB super-sub had to say after the game...
No BORUSSIA-PARKing the bus!
Borussia Mönchengladbach have won 11 games in a row at BORUSSIA-PARK, and making it 12 would be quite an achievement against FC Barcelona, even without the injured Lionel Messi. Read our full match preview here.
Footloose and fancy-free
The Bayern players have been limbering up at their hotel ahead of tonight's clash with Atletico. Top marks for use of the word "loosey-goosey"...
Carlo on Cloud 9?
Carlo Ancelotti is hoping to making it nine wins from nine as Bayern boss tonight, although Atletico Madrid will surely provide the stiffest test yet. Check out what the Italian had to say about life in the Bundesliga, and following in Pep Guardiola’s footsteps.
Recovered? We’re still coming to terms with the late drama of Tuesday night! Both the Bundesliga sides earn a point, but Dortmund will be much happier with theirs after twice coming from behind to deny Real Madrid. Leverkusen, meanwhile, will view their 1-1 stalemate on the French Riviera as two points dropped after conceding a last-gasp equaliser. And things won’t be much calmer on Wednesday as Bayern travel to Ateltico Madrid and Gladbach face Barcelona at home.
Enrique wary of Gladbach
Here are the Barcelona coach's thoughts on facing the Foals tomorrow...
Marc-Andre ter Stegen returns home
Speaking to the press ahead of facing his former side for the first time, Barcelona keeper Marc-Andre ter Stegen reflected on his time with Gladbach, but underlined that sentiment would be put to one side come kick-off.
Bayern's favourite Metro stop
What a gem of a find by the German record titleholders in the Spanish capital.
Borussia Mönchengladbach press conference
Here are the best bits of what head coach Andre Schubert and captain Lars Stindl had to say ahead of their game against Barcelona.
Cool, calm and collected
Robert Lewandowski has been in fine form this season and is looking cool ahead of Bayern's clash with Atletico Madrid.
Good news for Gladbach
With Barcelona in town, Borussia Mönchengladbach head coach Andre Schubert will be pleased to have almost a full squad to choose from on Wednesday night.
Hummels fit for Bayern
The Bundesliga leaders have received a boost ahead of their game against Atletico on Wednesday, with defender Mats Hummels available for selection after shaking off a knock.
Gladbach vs Barca: ter Stegen's homecoming
Mönchengladbach's home game with Barca on Wednesday is not only one for every Gladbach fan to mark in big red letters in the diary; it's also a guaranteed to be an emotional occasion for ex-Foal Marc-Andre ter Stegen, now the goalkeeper of Barcelona. Born and bred in Mönchengladbach, he became the first-choice 'keeper at the end of the 2010/11 season, helped the team stay in the Bundesliga that year and qualify for the Champions League play-offs in 2011/12. He made his last appearance in front of the Borussia faithful on 3 May 3014 before waving a tearful farewell to the fans. This will be his first return to the club. What a moment.
Kimmich on fire
We're fast running out of superlatives for this young man. A star at centre-back under Pep Guardiola last season, a successful UEFA Euro 2016 and now amidst a purple patch in front of goal: Joshua Kimmich may be the best young player in Europe right now. Have you added the 21-year-old to your fantasy manager XI? His goal against Hamburger SV on Matchday 5 would have earned you 14 points ...
