Jose Mourinho said Manchester United will be back in their "natural habitat" with their first Champions League match in 644 days.

“To be in the Champions League is just to go back to the natural habitat, season after season, for Manchester United,” the manager said. “I look forward to tomorrow and hope Old Trafford feels it in the same way we feel it. Our motivation’s high. We’ll try to qualify and enjoy that special knockout phase with the best teams in Europe.”

United won the Europa League last season.

“In the Champions League there are four or five teams with an incredible level of quality, of experience, of know-how and that’s what makes the difference. But there are many other teams in the Champions League with very similar qualities to teams in the Europa League.”
