Manchester United must produce their “best performance this season” to beat Barcelona and reach the Europa League last 16, says manager Erik ten Hag.

The sides, who shared a thrilling 2-2 draw at the Nou Camp on 16 February, meet in the second leg of their play-off at Old Trafford on Thursday.

“When you face such big teams as Barcelona you have to play your best, otherwise you don’t have a chance,” said Ten Hag.

United, who have not won a trophy since 2017, play Newcastle United in the Carabao Cup final at Wembley on Sunday.

They are third in the Premier League – five points behind leaders Arsenal – and face West Ham United in the FA Cup fifth round on 1 March.

“We have the opportunity,” said Ten Hag, who took over last summer.

“But the first focus point is always the next game and we can’t win the (Europa League) trophy this week.

“We have to keep in the same mindset that every day we want to give a better version of ourselves.”
