Yeah, but it wouldn't change the fact that Fabianski/Szczesny, Vermaelen, Walcott, van Persie and Fabregas miss half the season through injury and we have shitsters like Squillaci, Denilson, Diaby, Rosicky, Bendtner, and Chamakh coming into replace them. Schweinsteiger would get swallowed up by the mediocrity surrounding him just like most of our other good players do, as nearly all good players would.
We need to improve the areas where we'll be weak going into next season, that's where our money must go, not on an area of the pitch where we have some of best talent in world football. That's how I see it anyway.
