The last time Rooney had a serious injury he came back against Fenerbahce and scored a hat trick. Hardly good news for the Celts but this time its different.
Rooney gets frustrated quickly and he will no doubt be closely watched by Thomas Graveson, he is also known to let the opposition fans get under his skin and he will never have seen or heard anything like the Celtic support before. Old Trafford is normally a comfortable place where the home team can relax and not hear the away support. Not on Wednesday though as the Hoops support will turn it into an away game for united.
Celtic have targetted Rio Ferdinand's form as being a possible advantage after having watched him against Spurs on Saturday where he had the proverbial "shocker" Ferdinand passed the ball out of defence straight to opposition players in dangerous positions three times in ten minutes much to the disgust of the home support
