last season he played 38 matches with an injury and still scored 18 goals +3 assists so almost a goal or assist ever 2 matches.
thats not bad considering he played injured a lot and also played for allegri.
maybe not worth 12m per season, but i expect him to do better under a coach that plays attacking football.
also people saying sell him and get better, good luck. any striker scoring 20+ goals is going to go 70m these days.
