Injured against Young Boys (1:0 win), Juventus (4:4), Empoli (0:3 win), Hellas Verona (0:5 win), Fiorentina (postponed), Venezia (0:1 win).
Except for the Juventus game we haven't conceded when Hakan was missing.
So he didn't miss too many matches this season but we also can manage most teams without Hakan.
While last season he was injured against Real Sociedad (1:1), Atalanta (4:0 win), Genoa (2:1 win).
So basically he missed 8 games in a season and a half, that's nothing. I didn't count the games he was available but sat on the bench.
