Yea or basically somebody's taking into account that we're on the verge of losing 2 CBs in Vidić who's already gone and Rio, Evra at the LB where our second-choice-fullback is Büttner, we've got no cover for the RB unless we play Smalling and Jones there. Jones, Evans, Smalling, basically all the time atleast one of them is injured, if we promote Keane, that leaves us with 3 CBs between PL, CoC, FA and maybe EL. And that's just defence.
Then you've got central midfield where we've been lacking for years, Fletcher and Carrick are both aging, Anderson hopefully is gone, Cleverley is at best a squad player and then there's Fellaini, who's already entitled a flop by many. Our three wingers of Nani, Young and Valencia have been rubbish for last two years and it doesn't seem like anything will change in that department, then there's Januzaj, Mata, Kagawa ( out of which only Januzaj can be called a 'semi-winger' or something, the latter two won't give us pace that we need from the wings ) and possibly Danny, who I hope will be more of a #9 than a winger.
Incompetent manager is one thing, our squad aging, seriously lacking in certain positions for years, is another one. It's not all down to Moyes and staff being shite.
Edit: and no, 'one or two signings' won't cut it unless you want us to bleed out between Europe ( when we finally get there ) and league.
