The 21-year-old Rossi failed
to impose himself at Old Trafford in the three seasons he was at
the club and was transferred to Villarreal in the summer on a
five-year contract.
Sir Alex Ferguson was a reluctant seller of a player he rates so
highly and inserted a buy-back option in the deal.
Pires is not surprised by this and expects the talented striker to
return to Old Trafford in the future.
When asked about his thoughts on Manchester Uniteds option in
Rossi's contract, Pires told setantasports.com: "I expected it
because I know their mentality and they want to keep the good
players.
"They can't fail to miss such a good player so I have no doubts he
will return there.
"He is a very good young striker who already has a great mentality.
He is a goalscorer, you can see it every day at training.
°He is obsessed by scoring. He is tomorrows great attacker and I
enjoy playing with him because I don¢¥t know if he is going to stay
at Villarreal.
The Arsenal legend was then asked why Rossi did not impose himself
at Old Trafford.
"It is Manchester United, competition is tough there," he said.
"They don`t offer you gifts.
°I think he has learnt a lot up there. He has experienced what the
top level is.
"Today he is taking advantage of it and we are very happy to have
him here. He scores goals; hopefully he will continue until the end
of the season."
