The Netherlands international believes Bayern's decimation of Barcelona on Tuesday was as dominating as his side has been but has warned his teammates to remain humble.
Two goals from Thomas Muller, and further efforts from Mario Gomez and Robben himself gave the Bavarians the largest margin of victory in Champions League semifinal history, and the 29-year-old was stunned by the incredbile nature of the result.
“This was pure enjoyment. Fantastic. It's almost inconceivable how well we played. I don’t even think we ever played this well before," Robben told ITV after the match. “No, I really can’t [believe the result], but I think we can be very proud, because we gave them good competition in a game everybody said was 50-50.
“[Barcelona] have dominated Europe over the last five years, and to beat them like this in such a terrific way, I think we have to be proud. But on the other hand, let's be humble about it and enjoy this evening, because there's still a game to play and we have to be ready [for the second leg]."
Robben’s involvement did not come without controversy, however, as he appeared to benefit from Muller’s unpunished block on Jordi Alba in the build-up to his goal – but the winger refused to be drawn on the incident.
"I don't know [if we benefited from the referee’s decisions], I don't want to speak about this. I want to speak about the way we played tonight, because I think that needs to have the upper hand.
“We fought for every metre, and they only had one chance. In the end we really deserved the win."
