I would like to see Rodwell manage a few games and see if he is up to the task, otherwise we need a player similar to Fernandinho as him and Yaya can't play every game together and Garcia isn't good enough to fill in versus any difficult opposition. We get overrun in certain games playing two in the middle, so a 3rd top quality CM would be welcome.
Possibly someone like Strootman, Matuidi or Fernando, think we would have a good chance to sign any of these players who would all be an upgrade on Garcia and are not injured all the time like Rodwell. Possibly even Cabaya as a CM would be realistic, he was ready to leave in the Summer and is a pretty complete midfielder with the ability to play some nice long balls, something our team doesn't really have.
If Pelle doesn't go for a midfielder I would like a new LB as although Clichy does a good job, he really hinders our play by being so hopeless at attacking. Kolarov is almost the exact opposite in that he isn't good defensively (although improved on previous performances) but is decent going forward. So would look to shift Kolarov to some Italian team and try bring in a young attacking LB like Shaw or Digne. I can't think of any other LBs but think its something we will need to look into for next season, possibly promote an academy player?
