Arsenal midfielder Jack Wilshere has warned Manchester United not to fall for Barcelona's dirty tricks.
He is hoping United can win the Champions League for English football tomorrow.
Wilshere, whose Gunners side were dumped out of the Champions League by Barca, said: "They are so good at getting round the referee and helping him change his decision.
"Against us, Sergio Busquets was the main one doing it.
"We saw them dive against Real Madrid in the semi-final first leg, but it's convincing the referee to be on their side that is the biggest thing."
UEFA have handed Hungarian official Viktor Kassai the task of refereeing tomorrow's potentially explosive clash at Wembley.
