MICHEL Salgado believes Manchester United have to give his old nemesis Lionel Messi ‘double trouble’ at Wembley tomorrow as he backs them to stun the world.

Rovers’ own Champions League maestro admits he has been tormented by Messi in past El Clasicos but believes Premier League champions Manchester United have what it takes to conquer Europe.

Ahead of the Champions League final at Wembley between United and Barcelona tomorrow night, ex-Real Madrid stalwart Salgado has spoken about his experiences against the man widely regarded as the world’s best player.

The now Rovers full back, who won the Champions League twice himself, believes stopping Messi is the key for United.

He said: “I played five times against Messi and it is very difficult. The best way is to double up – that is very important. You have to try to get tight.”

Salgado played a key role in Rovers’ 1-1 draw with United at Ewood Park two weeks ago, as Steve Kean’s men matched Rooney and co throughout.

Now, he believes Barcelona will have difficulty in stopping Fergie’s side securing a double.

“It is not going to be easy for Barcelona to beat Manchester United for one reason,” he said.

“I know in terms of quality and passing, Barcelona is the best team in the world at the moment. But I played against Manchester United two weeks ago and they defend really tight, they have a winning character and Ferguson is very important in that.

“Generation after generation, he has been able to convince everybody to learn. All the youngsters that have come into the club have learned to be winners.

“They are not playing fantastic football but they are really quick on the counter-attack and they defend really well. They will have a good chance – no doubt about that.”
