Well, lets look at two things, firstly, A2M is suggesting a panic buy can't be a good player...... that is completely ridiculous in the first place. OMG last second of the transfer window, offer 300mil for Messi...... panic buy.... and he'd be awesome.
Aside from that, we bought Mert, crap, Benny, utterly useless, Park, our one makes Utd's one look good...... we're paying him and he'll leave in 18 months now whatever we do, Santos, cack, Arteta. They were all panic buys, whoever you could get in the last day or two basically, whoever was available, not first choice, not the best choice for the team or positions we needed, just whoever we could get.
THen the fact that, Arteta isn't playing the same position as Fabregas, we've basically bought an out of form attacking central mid to play as DM to cover Song who pretends to be the DM but goes forward a lot and like the other day, without Arteta covering him showed what a useless idiot he is defensively.
He has no idea what is going on around him, NEVER looks behind him to check for danger and always reacts late to everything, usually resulting in a foul when chasing someone.
We bought the wrong player for the wrong position because he was all that was available. The fact that he is both a better DM than Song, and not an awful player is neither here nor there.
I pray Wenger will drop Song if Wilshire ever gets fit again, with Ramsey/Wilshire attacking and Arteta covering their ass, with Wilshire, another player who spent a season covering Song's ass, also helping out defensively when needed.
Overall 10mil for an older player who hasn't looked great for 2 years at least, who we're playing out of position, when we could have got a better attacking central mid OR a better DM had we gone out earlier and got one before it was too late.
End of the day, that 10mil could have gone on Hazard instead, or on Diarra, or Gotze, or a bunch of better players. It's STILL 10million and we still need a long term creative central mid who is better than Arteta and we STILL need a DM who is better than Arteta. It's not horrendous business by any means, its not good business though.
