Coach Fabio Capello is yet to confirm whether he intends to select Rooney for one of England's tougher Euro 2012 qualifying matches.

The England coach will need to make sure his striker is in the right frame of mind though as his side look to build on Friday's 4-0 triumph over Bulgaria.
But Switzerland coach Ottmar Hitzfeld said he expected his team to be facing an England side containing Rooney tomorrow.
The German coach said he doubt whether off-field worries were a reason for striker's poor World Cup performances.
"I expect Rooney to be on the pitch," he said. "Fabio Capello is not able to leave a player of his class out.
"I am no psychologist but Wayne Rooney is looking sharp and I am sure he will perform well. The only reason he didn't do well in the World Cup was that he was injured beforehand and didn't have time to make his fitness up in time for the tournament."
Meanwhile, Switzerland's London-born defender Scott Sutter this morning admitted he had been following the Rooney reports.
The Young Boys player, who made his international debut against Australia on Friday, thinks Switzerland might be able to profit from the distraction.
"Wayne Rooney is an amazing player," he said. "When he's on his game, it is hard for anyone to stop him.
"But with these things going on in his private life, it depends how mentally strong he is and whether he can put it to the back of his mind and play like the way we know he can.
"I read all the papers online so I have been following what is going on. Obviously, it is a distraction and maybe he will not be as totally focused on the game.
"We have to hope Wayne Rooney doesn't play as well as he can. But whether something like that will affect him, I don't know, we will see."
In total, Capello has 22 men available in his England squad. He decided not to call in a replacement for ankle injury victim Michael Dawson as in Phil Jagielka, Gary Cahill, Matthew Upson and Joleon Lescott he already has four centre-halves.
In addition, Watford's Scott Loach will make the journey as third-choice goalkeeper as Scott Carson has withdrawn due to a family bereavement.
