Alex Ferguson upset by display as Leeds beat Man Utd

Rooney and Berbatov trudge off after Man Utd's shock defeat by Le

Manager Sir Alex Ferguson did not hold back in criticising his players as Manchester United were dumped out of the FA Cup by League One side Leeds.

Ferguson said Leeds had deserved the victory as their rivals won 1-0 in a big upset at Old Trafford.

"I didn't expect that performance, it was shocking. I've no complaints about the result," said Ferguson.

But he did complain about not enough injury time being played, describing the five minutes as "an insult".

He questioned referee Chris Foy's timekeeping and stated: "That is an insult to the game and the players out there."

Ferguson has already served a two-match ban this season for criticising a referee.

The Football Association handed the 67-year-old a four-game ban, with two of those suspended until the end of the 2010/11 season, for his comments about referee Alan Wiley's fitness.

Ferguson was also fined £20,000 and warned about his future conduct.

Sunday's second half was punctuated by several petty disputes and an injury to Leeds goalscorer Jermaine Beckford and there were five substitutions before the additional time was shown.

However, Ferguson turned most of his ire on his players after Manchester United were defeated by lower league opposition for the first time since they were beaten in Bournemouth in 1984.

"Leeds deserved to win. They got breaks at times but deserved their luck - I'm disappointed," added Ferguson.

Beckford's 19th-minute goal was enough to secure Leeds a famous victory at Old Trafford - their first since 1981 - but Ferguson was frustrated at his team's overall display.

The Scot had picked a side including the likes of Gary Neville, Wayne Rooney and Dimitar Berbatov, while the less experienced Danny Wellbeck and Fabio da Silva were also on show.

He told MUTV: "We did speak about Beckford's pace up front.

"We were caught napping really, it was a bad goal for us to lose. The whole performance in the first half was bad. We never got going and the quality of the passing… the whole performance was just bad.

"I don't think any of the players can say they had a good day. Maybe only [substitute Antonio] Valencia, when he came on, can say that. Even then it took us about 10 minutes to get the ball to him.

"You expect us to get a goal at Old Trafford and the intensity of our game improved a little bit in the second half. We had a lot of chances in the box but on the day we didn't take them."

Assistant manager Mike Phelan admitted the defeat was a "major blow" to United's season.

"We wanted to progress in this Cup," Phelan told BBC Sport.

"We need to be in finals in Cups like this. To go out at the stage we have done is not acceptable."

Manchester United now have to dust themselves down for the Carling Cup semi-final against local rivals Manchester City on Wednesday and Ferguson suggested that many of the team that faced Leeds would pay the price for an uncharacteristic display.

"We have to get this result out of our system as quickly as possible," commented Ferguson.

"We have a semi-final on Wednesday and a lot of these players won't be playing.

"You have to view this performance in the right light. We'll make sure we're ready for Wednesday now. We had a team in mind but there will maybe be a few changes for that."
