Sevilla boss Julen Lopetegui is wary of facing an improving Manchester United in their Europa League semifinal.

United stand between Sevilla and a place in the Europa League final, with Lopetegui admitting Ole Gunnar Solskjaer has finally got the Reds back on track.

“I think United are the best United in the last few years," said Lopetegui, whose side face United in Sunday night's semi-final.

“They've found their football, they have not lost since January in the Premier League, such a competitive league, and they are in the right place.

“They're a total team in many respects and are going to force us to play a great game if we are going to be able to compete with them."
