If Milan will offer anything around 18M or more I'll say "Well done, guys! Well done!". I think he is a good guy but we won't miss him at all. It's fair to say no other club is interested in Balotelli, only Milan.
And some numbers from this season:
Edin Dzeko - 29 games - 1488 minutes - 11 goals - 4 assists - 99,2 min/goal
Carlos Tevez - 29 games - 2031 minutes - 9 goals - 12 assists - 96,7 min/goal
Sergio Aguero - 25 games - 1709 minutes - 10 goals - 3 assists - 131,5 min/goal
Mario Balotelli - 20 games - 825 minutes - 3 goals - 2 assists - 165 min/goal
And from last season:
Edin Dzeko - 43 games - 2402 minutes - 19 goals - 9 goals - 85,8 min/goal
Carlos Tevez - 15 games - 700 minutes - 4 goals - 3 assists - 100 min/goal
Sergio Aguero - 48 games - 3459 minutes - 30 goals - 12 assists - 82,4 min/goal
Mario Balotelli - 32 games - 1883 minutes - 17 goals - 2 assists - 99,1 min/goal
I think these numbers say something...
