Arsenal midfielder Jack Wilshere is urging Manchester United to get in the faces of Barcelona tomorrow.
England starlet Wilshere saw his Arsenal side ousted by Barca in the last 16.
And the Gunners midfielder said: "The thing with Barca is three passes - bang, bang, bang - and they're through. So you have to get in their faces.
"You have to stop the players like Xavi, Lionel Messi and Andres Iniesta who can just kill you.
"But if you can get in their faces they ease off in the second half and you really have to go for them."
Wilshere, 19, added: "United have a better chance than we had. They have the likes of Ji-Sung Park and Antonio Valencia who are runners and can stop players.
"United should use just Wayne Rooney with Valencia and Park helping out behind them.
"For most of it, though, they will be defending because that is what Barcelona make you do."
