Well, you need to take one thing in accound. We allways try to have an "extra" player. Like Borriello, Bendtner, Anelka, Osvaldo.
Consider that allmost our entire forwards bench is gone. What will we do, spend money on 2 new strikers to sit on our bench ? I would be all for getting immobile and some cheap experienced player. Drogba suits the category for the latter.
I wont comment on evra, because i will get perma banned for excessive racism if i do.
But some people need to realise going "so yeah, we need leftback, central midfielder, 2 starting wingers and 2 replacement wingers, and 2 bench strikers" is completely unrealistic.
So seeking cheap deals for non starting players with experience is good.
By doing that, we could save money, to spend on those wingers y"all want.
