Barcelona defeated Arsenal 5-1 on aggregate during the two legs of their Champions League tie.

But Arsene Wenger rejected the notion that the big Spanish clubs and Bayern Munich have become unbeatable.

"They are not. And the regret I have from the two games against Barcelona is that maybe they were more beatable than ever before when we played against them. They are not so much out of reach," Wenger insisted.

Wenger believes the Premier League clubs are at a disadvantage due to what he believes is the perceived strength of their league.

"Maybe the Premier League has become the Champions League for English teams. Because every game is so difficult in the Premier League that maybe we suffer a bit in Europe," Wenger said. "Barcelona can walk through their games before they play against us. They played on Saturday afternoon with a team that after 20 minutes was 3-0 up. ... They can select a little bit how much they go for it. In the Premier League you cannot."

Outside of Chelsea's improbable win in 2012, English clubs have struggled recently in the Champions League.

"Football belongs first to the players and the quality of the players. I believe that with more income in England the best players will slowly all come to England, and that will be the answer," Wenger said. "For years we were in England always in the last [four]. Sometimes you played an English team in the quarterfinals or the semifinals of the Champions League. I believe that will come back again, I don't worry about that."
