I hope you're not serious
Manchester United will be looking to exploit both the flanks and our lack of pace in central defence. I am fairly confident that Enrique will do a solid job on the left and Downing always puts a decent shift in to help out.
On the right Kuyt covers well and playing alongside Kelly has a very good understanding which works well in defence and attack.
I'm more concerned if Johnson or Flanaghan play on the right. I like Flanagahn - I think he is one for the future and shows bags of potential, but this isn't the game to bring him back into the frame. It's a high profile fixture. If he plays then Ferguson will see him as a weak link, they would be attacking down the left and doubling up and using pace to beat the defenders into the centre. If we concede one or two goals from that flank then he would get dogs abuse from the fans and any confidence would evaporate - leading to a hatful of chances. The fullback position is one where you don't want to change it around once you've kicked off if you can help it.
If Johnson plays then I'd be worried simply because he isn't a good defender. Certainly not of the class of Enrique.
I'd say the only fullback at the club at the moment worth his position is Kelly. I really like the lad and I like his understanding with Kuyt.
But failing him, just for this fixture I would want someone that could use their experience and positioning to give our team the best possible chance. Gerrard - it is a fact - gets away with more than other players would - so an opportune kick on their lightweight forwards could mean the difference between us holding the line or caving in.
I hope that I'm proven wrong, but if I were Ferguson I would be literally jumping for joy to see an 18 year old with less than 10 appearances in his career facing my attacking line.
