Former Manchester United defender Gary Pallister believes the departure of Cristiano Ronaldo will be the making of Wayne Rooney.
"Wayne is the type of player who needs a challenge and Ronaldo going has given him a new one," Pallister told the Manchester Evening News.
"He'll have seen Cristiano become World Player of the Year and, though I don't think he is the type who says `look at me I am a superstar,' I believe that title might be one he thinks he is capable of achieving.
"I wouldn't bet against him doing it one day. He has got the stage, he has got the hunger and desire and he certainly has the ability in his locker to achieve it.
"It looks like he will now get his more favoured position for most of the season and with that I think he will certainly score more than 20 goals and is capable of the 25 to 30 bracket.
"He contributed to Arsenal's downfall in the Champions League in that disciplined role but they certainly won't be looking forward to facing him on Saturday in the role and mood he is in."
