Balotelli's the one I really want. I'm sure Costa's a quality player and currently much more reliable than Super Mario, but you don't have to know Costa's game well to know he doesn't have anything like the ability Balotelli has; almost nobody does. I know he's a risk, he could end up moving on in a few years having never made the strides forward in his game that will turn him into a striker as good as any, but, there's also the very real possibility that, with Wenger's guidance, he could realise his massive potential. He has every single attribute I value in a striker; such a rare mix of technique, speed, power and intelligence - there's just not many 'complete' strikers around these days.
And even if it didn't work out, he'd still be much more fun to watch than Olivier Giroud!
