Alex Ferguson lauds 'incredible' Ryan Giggs following vintage display Manchester United boss Sir Alex Ferguson backed Ryan Giggs to continue playing for the club for another year after the veteran midfielder's performance in Wednesday night's 1-0 FA Cup third-round replay victory over West Ham. Giggs, named as captain for the evening, delivered a virtuoso display in the contest at Old Trafford as United set up a fourth-round home clash with Fulham. And referring to the 39-year-old after the game, Ferguson told MUTV: "He will play for another year. There are no signs of tiredness or weakness in his game, his quality is still there, he has fantastic balance and he has appetite for it. United's goal came in the ninth minute from Wayne Rooney, who was back in action after sitting out their last five matches due to a knee injury. The England striker turned in Javier Hernandez's square ball from close range, and after taking the congratulations of his team-mates, then paid his respects to his late sister-in-law, kissing his hands, looking to the skies and raising his arms as he walked back towards the halfway line. United had chances to extend their advantage but could not take them and West Ham grew into the game after the break. The visitors had a penalty appeal for handball against Rafael waved away by referee Phil Dowd, who then awarded a spot-kick at the other end with just over 10 minutes remaining for a similar infringement by Jordan Spence, only for Rooney to waste the opportunity by blazing high over the bar. It leaves United with a record of four penalties scored and five missed for the season so far and Ferguson said: "I don't think it is just one of those things. West Ham manager Sam Allardyce was unhappy with Dowd's decision-making on the two handball incidents and suggested the referee lacked courage. Allardyce said: "It was very disappointing that we were not given a penalty at 1-0 in the second half for Rafael's handball, which was blatant and clear for the referee to see in the position he was in. He couldn't find the courage to give it unfortunately, and he then went down the other end and there was a very similar incident with Jordan Spence and it was given. That is a very big disappointment for me - the lack of consistency in that area.
