Darren Fletcher believes Manchester United will have cause to be thankful for Wayne Rooney
's last-gasp Carling Cup winner when they visit Arsenal on Sunday.
Not only did Rooney's stoppage-time header book a Wembley showdown with Aston Villa next month, it also avoided United having to face a draining extra half an hour against Manchester City - time that would have sapped legs and made recovery far harder for the encounter at the Emirates.
"Apart from winning us the tie, the good thing about Wayne's goal was that it saved us going into extra time," said the Scotland midfielder. "That would not have been the ideal preparation for a visit to the Emirates because we know how important this weekend is.
"But that is what being a Manchester United player is all about - a massive semi-final during the week then a few days later another one in the league."
