Arsène Wenger will give the Europa League extra attention this season because of the number of quality sides in the competition.

Both Manchester clubs were eliminated from the Champions League on Wednesday night to leave Arsenal and Chelsea as the Premier League's two representatives in the knockout stages.

It has been suggested that United and City will not prioritise the Europa League as they challenge for their domestic title but Wenger is not so sure.

"When it gets to the quarter-finals the Europa League becomes really serious," he said.

"When you look at the teams who are in the Europa League this season, there are some good teams in there, it is a very interesting competition quality-wise.

"After that, what kind of involvement the clubs will decide to put in, I don't know, but it will be a good competition.

"It is difficult to predict how it [the Manchester clubs' exit from the Champions League] will affect the title race because it is always a big disappointment to go out of the Champions League, how the two teams will respond to that, I don't know.

"I cannot predict that, my problem is Arsenal."
