FA Cup Replays

Quarter final replays tonight for the FA Cup tonight and I dont see any major shock in store for United. Following the first game at the Riverside I got the distinct impression Middlesboro felt that they had lost their chance. In an interview after the game Boateng was quoted as saying that the ref had cost them their place in the semi finals. A defeatest attitude and one that is hard to escape from. I am hoping for a relatively straight forward victory fo us tonight, providing our attitude and team selection is right.
I think Chelsea will find things more difficult however. Spurs were unlucky the last time out and are playing with great flair and confidence at the moment. They will be looking for some domestic trophy to appease their fans and this is their only chance. They will be up for the game tonight having already beaten Chelsea at White Hart Lane this season. Chelsea on the other hand may have their eyes on other prizes and may be content not to exert themselves too much tonight. This has the makings of a classic cup tie and I think I might just side with Spurs after extra time.
I hope I am right.
