Munich - Thomas Müller claimed FC Bayern München “were on fire” after the Bundesliga leaders put six past FC Porto to overturn a 3-1 first-leg deficit and book their place in the UEFA Champions League semi-finals.

Speaking after what turned out to be another memorable night at the Allianz Arena, the 25-year-old had words of praise for the Bavarians' team effort and admitted his pride at having become the all-time German top scorer in the competition.

Question:Thomas Müller, what a game! Can you put Bayern’s performance into words?

Thomas Müller: We were excellent. We were expecting a lot from ourselves tonight and managed to produce a top-notch performance. [In the first half] we created a lot of chances and didn’t allow Porto any. It was a fantastic team effort. We were a bit tired after the break, but now we’re really happy and knackered.

Question: Did you expect to win by such a big margin?

Müller: You can’t really expect to be 5-0 up at half time after having managed only two attempts on goal in the first leg. We said to ourselves we’d need to stay calm and wait for our opportunity, but thankfully we didn’t have to wait long for our first goals to arrive. We were on fire in the first half and every goal gave us an extra boost. Also we avoided making crucial mistakes early on unlike in the first leg.

Question: Was this win down to the sheer will power Bayern demonstrated?

Müller: Last year in the semi-final against Real Madrid [where Bayern had to overcome a 1-0 deficit only to lose 4-0] we wanted too much. Tonight we were very lively in attack. It was a fantastic home performance, we did a lot of things right. Tonight’s victory was a statement. We were under pressure but showed we could cope with it and win such a crucial game. It’s a great feeling.

Question: What was on your mind when Porto pulled one back?

Müller: We were aware they only needed two more goals of course. Even at 5-0 the tie wasn’t over. We stayed cool though, despite being tired towards the end of the game.

Question: You’re now on 27 goals in the Champions League, making you the all-time German top scorer. What does it mean to you?

Müller: I’ve always said I’d like to be top scorer, the reason being I want to score to help the team.

Question: Was this Bayern’s best performance so far this season?

Müller: You probably wouldn’t be asking me this question had we played as well, but not won. We always try to give it our all, but you can’t be at your very best in every single game. We were phenomenal against Porto. Now we’re looking forward to the draw.
