Team News: Manchester United v Rangers
Sir Alex Ferguson will check on Mikael Silvestre before naming his "strongest team" for Manchester United's Champions League date with Rangers.
The French defender has been out of action since picking up a knee injury nine days ago and unless he trains on Monday it looks as though he could miss out.
Roy Keane will return to lead United after being rested over the past 10 days and Phil Neville is also expected to make a comeback in midfield, probably at the expense of England team-mate Nicky Butt.
Should Silvestre fail to make it, John O'Shea is set to continue at centre back with Quinton Fortune on the left.
Ferguson has hinted that he is ready to involve 19-year-old Scotland international Darren Fletcher in a central midfield role alongside Keane but Eric Djemba-Djemba is also in contention, while 18-year-old Cristiano Ronaldo competes for a starting place on the right.
Brazilian World Cup winner Kleberson returns to the squad after being out since the end of August with a dislocated shoulder but Paul Scholes, Ole Gunnar Solskjaer and Wes Brown are all missing as they recover from surgery.
Manchester United (from): Howard, G Neville, Ferdinand, O'Shea, Fortune, Ronaldo, Fletcher, Keane, P Neville, Giggs, van Nistelrooy, Silvestre, Butt, Forlan, Djemba-Djemba, Bellion, Kleberson, Lynch, Carroll.
