Ruud van Nistelrooy's hamstring problem is Manchester United's major injury concern ahead of tomorrow night's Champions League encounter with Olympiakos at Old Trafford.
The Dutchman came off the bench to grab his fifth goal in four games in the 3-1 win at Charlton on Saturday but suffered a recurrence of the strain and was taken off at half-time against Bayer Leverkusen last week.
Juan Sebastian Veron (flu) and Mikael Silvestre (knee) are over the problems which kept them out of the Charlton game while Ferguson is confident Nicky Butt will recover from the back injury he picked up at The Valley.
Gary Neville is almost certain to start his first game in four months, probably at the expense of John O'Shea.
PROVISIONAL SQUAD: Barthez, Ricardo, Carroll, G Neville, P Neville, Silvestre, Blanc, Ferdinand, O'Shea, Tierney, Roche, Veron, Beckham, Butt, Veron, Giggs, Stewart, Scholes, Pugh, van Nistelrooy, Solskjaer, Forlan.
