I won't bore you with Balotelli's past, who he played for when he was 11, how many goals he scored for them, what his favourite colour as as a child etc., what I want to talk about is his impact on the Liverpool team.
Liverpool nabbed Balotelli for a fee reported to be around £16m (BBC Sports) and I think this is a pretty good price. If you go on twitter you'll see all the comparisons like the fact that Balotelli only cost Liverpool £5m more than Fulham paid for Ross Mcormack and if you look at it like that then it probably is good value. However, don't forget, Milan were trying to sell him and I can imagine it's incredibly difficult to push the price up with someone who has a history like Mario does. I think only time will tell if it was good value for money but he definitely represents a huge risk.
