I still think Balotelli would be a fine signing for us.
He's got plenty of experience on big stages, enormous talent, and he's still got room to improve. Signing him would strengthen a weak area considerably and boost our morale and our profile. That's about all you get for £25-30m these days.
A cursory glance at his record and his highlights shows he's been fairly prolific in recent times, and they're not all penalties either. I'm not sure how you turn being arguably the world's best penalty taker into a negative anyway! We can definitely make use of dead ball skills.
He's got the quality for the highest level, it'd be down to Wenger to work on his attitude.
