The arguments against him that aren't positively unfounded strike me as being nitpicking, really, more than valid reasons not to sign him. He isn't lightning quick, he's not the best passer in the world, he doesn't have Scholes' impeccable timing, etc. We need a reinforcement, not a perfect box-to-box midfielder (there's no such thing around these days anyway). People should stop considering him as the only midfield signing we'll ever make and start considering what he would actually bring to the table. We can buy Gündogan or whoever will be flavour of the month next summer. The fact is we need someone now, it's quite urgent.
Saying he wouldn't close the gap between ourselves and Munich or Barca is neither here nor there. He wouldn't widen it either, quite to the contrary: He would strengthen our options. That will do for now. What is it that people expect? That Moyes, in his debut season, completely transforms the team and overtakes Bayern Munich in style? What we need to begin with is a good league campaign, keeping up with our rivals in that respect. We have the foundations for that already, we just need to add a couple of players to the squad and we're good to go. But time is bloody well ticking.
