Barcelona coach Ernesto Valverde was impressed by Jose Mourinho's Manchester United for today's clash in Washington.

Barca won 1-0 thanks to a goal from Neymar.

"Obviously it hasn't been well lately, but I mean they won the Europa League," Valverde said.

"This year they are going to be in the Champions League. Their presence by itself is impressive. They impress.

"I think they are going to be a really hard team to beat.

"For me, they are contenders to win and they are going to be hard to beat in the Premier League and the Champions League.

"I wouldn't want to face them in the Champions League."
