Fergie warns stars they could be dropped for Carling Cup
Sir Alex Ferguson has warned that several Manchester United stars will be dropped for Wednesday's Carling Cup semi-final at Manchester City.
Ferguson also raised fresh doubts over the Old Trafford future of Nemanja Vidic after the Premier League champions' FA Cup humiliation by League One leaders Leeds United.
Jermaine Beckford's goal ensured United's first FA Cup defeat against lower league opposition and first third-round exit since 1984.
While youngsters such as Gabriel Obertan, Darron Gibson and Fabio da Silva struggled to justify their selection against Leeds, their more experienced team-mates also failed to perform against a team lying 42 places behind United in the football pyramid.
Having planned to field a similar blend of youth and experience against Roberto Mancini's City on Wednesday, Ferguson's anger at the performance of the majority of his players prompted the 68 year-old to warn of major changes at Eastlands.
Ferguson said: "You have to bounce back. That's exactly what you have to do - get it out of your system. You have to get over these kind of results quickly, but we have a semi-final on Wednesday and a lot of these players today won't be playing.
"You have to view that performance in the right light, but we have to get ready for Wednesday now. I had the team in mind, but there may be changes now.
"I didn't expect that. I was shocked at the performance. Leeds fought like tigers, but you expect that from any team coming to Old Trafford."
Turning back to the performance of his own players, he said: "I don't think any of them can say they had a good day. Only Antonio Valencia, when we got the ball to him, but it took us about 10 minutes to do that."
Serbian defender Vidic, who had been named in the starting line-up against Leeds, is a doubt for the City game after telling Ferguson that he could not play against Simon Grayson's team after sustaining an injury during the pre-match warm-up.
When asked about Vidic after the game Ferguson appeared exasperated by the late withdrawal of a player who has emerged as a summer target for Real Madrid.
Ferguson said: "I couldn't tell you what the situation is with Nemanja. I couldn't tell you at all."
Beckford's goal, his 20th of the season in all competitions, was a result of poor defending by United, who allowed the forward to latch on to a long ball from Jonny Howson before guiding his shot past goalkeeper Tomasz Kuszczak.
Ferguson admitted that his defenders paid a heavy price for their lack of concentration. He said: "We spoke about it before, that Beckford has got a lot of pace, but they were caught napping.
"It was a bad goal for us to lose but the whole performance from us was bad in the first half."
United could not find a winner in five minutes of stoppage time, but Ferguson insisted referee Chris Foy should have played more.
He said: "The referee gave five minutes of injury-time. That is a insult to the game and to the players out there."
