Arsenal midfielder Denilson has warned Manchester United that it will not be 'men against boys' when the two sides lock horns at Emirates Stadium.
Patrice Evra claimed the Red Devils were on a different level to the Gunners following their convincing semi-final victory in the UEFA Champions League last season.
Denilson remembers the Frenchman's comments and is determined to show on Sunday that he has matured as a player.

"We lost two games against Manchester United in the Champions League but we learned from both," said the Brazilian.
"I remember Evra saying it was men against boys. We're not boys any more, I am a man and I'll show that on the pitch.
"I don't like to talk too much off the field, I just want to show it out there."
Denilson has also defended manager Arsene Wenger for putting his faith in youngsters rather than signing established stars.
He said: "A lot of people say Arsene Wenger goes only for young players. We are young, but we have many players with experience now.
"Cesc Fabregas is young but he is very experienced. You can't call us kids any more.
"It doesn't matter that I'm 21 and I need to show on the pitch that it doesn't matter how old I am.
"This season is a test of our character, but we're more experienced than last season.
"We have to beat United, it doesn't matter whether it's 1-0, 2-0, whatever. But we are very confident."
