Ex-Manchester United striker Dion Dublin says Paul Pogba and Romelu Lukaku must up their game if the Red Devils want to beat Barcelona on Tuesday.

The Red Devils will head to the Nou Camp down 1-0 after Wednesday night's loss to the Blaugrana in the first leg of their Champions League quarterfinal.

And Dublin has called on Pogba and Lukaku to raise their games

He told BBC Sport of the need for United to find an attacking spark, both in midfield and up front: "United did not manage a shot on target on Wednesday, and they did not really use the ball well enough when they got possession.

"Pogba was the player expected to play the biggest part in unlocking the Barcelona defence, but we did not see enough of the creative side of his game.

"He will have to do much better next week, but he can only do that if his team-mates are making the forward runs that allow him to play those sort of passes.

"Lukaku should be doing exactly that. He did not manage a single shot in the first leg but I actually thought he played well.

"He held the ball up and was very reliable in possession, but all of his work was a long, long way from goal.

"If United are to have any joy at the Nou Camp, they need to get him in the box and give their wide players more to aim at, because firing the ball into the Barcelona area was clearly part of Solskjaer's plan."
