you really can't lay the blame at Auba's door, just look at how many goals he scores from out on the left wing and with a generally crap team around him - it's a miracle tbh
but you're right we should be grown up in any negotiations and not just chuck too much money at him, after all at some point he could slow down dramatically - just look how shite laca's been this season (one good goal on sunday doesn't forgive a bucketload of misses)
