"I know maybe in England the focus is more on the Champions League," he said. "Maybe it's because the English teams are getting used to winning trophies in the Champions League: if you look at the semi-finals most of the teams are Spanish or English.
"Every player wants to play Champions League but I am not the type of person to say it is a step down.
"The Europa League is a very good competition also and we will try to go to the end.
"I played this competition with Borussia Dortmund and it is a difficult competition and when the Champions League teams come down after their first group stage it becomes a very good competition."
