Bayern are expected to dump Arsenal out of the Champions League tonight.
But Lahm insisted there has been a shift of power in Europe.
He said: "It is a surprise to have no English teams in the quarter-finals.
"They have a strong league and have gone quite far in the past, so it is a big surprise. A lot of teams have caught up. We are here, Borussia Dortmund are here."
And Bayern coach Jupp Heynckes concluded: "The English teams were strong. Now there are three Bundesliga teams. There are always changes - that livens up the Champions League."
