Ashley Cole faces two weeks on the sidelines following Chelsea's FA Cup victory over Manchester United Van Persie, who has now failed to score for United in his last nine appearances, volleyed over from seven yards out, while Hernandez was denied by a superb save from Petr Cech. "We lacked the composure to win the game," Ferguson said. We had a lot of possession but didn't make the best use of it and on the counter they can cause you bother. We didn't lose another goal but I couldn't see us scoring ourselves, apart from Robin van Persie's volley and Cech made a good save from Chicharito. The first half we were absolutely comfortable, I couldn't see them being any great threat, but the goal changed the game. Ferguson admitted to a feeling of déjà vu when watching Ba's goal, a volley at full-stretch following Juan Mata's probing chip, as the Senegal striker scored a very similar goal against United during his Newcastle days. We spoke about Ba, we had the experience from Newcastle a couple of years back when he scored exactly the same type of goal. Ba seem nonplussed by his man of the match award and, like Ferguson, said the goal reminded him of his strike for Newcastle. "It was a brilliant pass from Juan," said Ba.
