"We are lucky to still be in the FA cup" -- Sir Ferguson

Sir Alex Ferguson has admitted Manchester United are lucky to still be in the FA cup.

United swept into an early two-goal lead against Chelsea at Stamford Bridge, only to crumble after the interval, this gave Chelsea a chance to score two-goal.

“We are lucky to still be in the FA Cup,” said Sir Ferguson.

“We ran out of legs. Our two full-backs, Rafael and Patrice Evra, were knackered and the two centre midfielder players tired badly and we kept giving the ball away.

“I detected there were some signs of tiredness. You have to understand the problem is the emotion and intensity of Tuesday night had taken its toll on one or two of the players.

“Understandably I have no problems with that part but it made it a long day for us anf they were by far the better team in the second half.”

“We could have been four up in the first 25 minutes” he said

“Wayne and Javier’s goalscoring has been great this season.

“We need that because by the end of the first half I detected our legs were starting to go.

“It was a very good save by David de Gea near the end. If we were out there would have been no doubt about that.”

No date has been set for the replay.

The Football Association are expected to offer an update tomorrow.

Nani limped off with a hamstring injury just before the break.

“I don’t think it is serious but he had to come off,” said Ferguson

“It was unfortunate because he was playing well.” He said.

Ferdinand told MUTV: “We gave them the impetus to claw their way back into the game. We played some great football at times but were so careless at times. If you are careless you are going to get punished. That was the case.

“There wasn’t a mental reaction to Tuesday but maybe physically you could see it in a few of the guys’ legs, and as the game stretched and became a bit more open there were some tired legs out there.

“But that is no excuse. We should have had the game sewn up before then and with the experience out on the pitch we didn’t utilise it the way we should have.

“But we are still in the cup. Wembley is waiting for one of us to go through and hopefully it is us.

“We go to Stamford Bridge for the replay with confidence. We have the tools. We have been there before this season and done well, and with the squad we have we don’t fear going anywhere.”
