Nemanja Vidic remains doubtful for Manchester United's Barclays Premier League match against Portsmouth on Wednesday night at Old Trafford because of a virus.

The Serbia centre-back was forced to miss the FA Cup victory over Tottenham on Sunday after being taken ill.

Paul Scholes is pushing for a place in the starting line-up after a 25-minute appearance in the fourth-round tie, three months after a knee operation.

Louis Saha (knee) and Gary Neville (ankle) remain sidelined through injury.

Czech Republic striker Milan Baros is set for his Portsmouth debut and skipper Sol Campbell should return following a back injury.

Baros looks certain to start after David Nugent flew to Germany for a hernia operation later this week, leaving Pompey with just one other available forward in Benjani Mwaruwari, who is troubled by a neck and shoulder injury but is expected to play.

Sean Davis, who made his comeback as a substitute from a month-long absence with a foot injury last Saturday in the FA Cup win over Plymouth, is pressing for a starting role. Noe Pamarot and Lauren could miss out.
