Balotelli.

No, please no.
Get rid of one extremely talented player with a penchant for getting into trouble, for someone less talented but equally liable to get into trouble on, and in Balotelli's case, off the pitch. And whereas Suarez seemingly got on with his fellow players, and didn't cause trouble, at least in the dressing room,

and got on with the manager, the same can't be said of Balotelli.
Love him or hate him, Suarez always gave 100% and wanted to play every minute of every game. He had a will to win stronger than any player I have seen. Occasionally he may have crossed the line, but I'd rather have someone with those positive traits, than someone not bothered half the time.
If Balotelli was a good buy, Milan would not want to sell, there would be potential buyers queuing up, and he would be sold for a lot more than Milan bought him for, but none of that is apparent with Balotelli, which rings some alarm bells for me.
A few years of getting the Liverpool dressing room settled, positive and pushing in the right direction could be ruined by Balotelli. Hopefully not if it goes though, but it is not a bet I would be making.
Let the Balotelli media circus begin. And be a sideshow to disrupt any title ambitions.
