Rooney needs time to recuperate from a nagging ankle injury but with suggestions that he also needs to get his head right after allegations over his private life, Sir Alex Ferguson claimed this week that ''it will be two to three weeks''.
However, there is speculation that Rooney could be set to for a shock return against Sunderland at the weekend having been left at home for the 1-0 win over Valencia in the Champions League.
ESPNsoccernet understands that Capello is now seriously considering picking Rooney when he announces his squad for the Euro 2012 qualifier on Monday and the England medical staff are in "day-to-day" contact with the United doctors to assess the condition of his ankle.
"At one time it was three weeks, now it might be two days!" an insider revealed.
While Ferguson has plenty of options in his attack, it is a different case for Capello who needs Rooney with several strikers out injured. Carlton Cole, Peter Crouch and Darren Bent are the only forwards available and, despite his dip in form, Rooney is still seen as a vital player for his country.
Capello's usual policy is to call up all players who have short-term injuries for assessment by his own medical staff rather than rely on the diagnosis of club doctors.
