14-15 players? We had 20 players who played a part over the season, down to Buffon's appearances.
Obviously there were big injury concerns on and off all season for certain players - Ramsey (shock), Chiellini, Morata, Dybala (most harmful) and Arthur, which all had an impact on the depth and cohesiveness of the team.
I still think that empty stadiums played a big part for us, but others can disagree. This is a club that always excelled under pressure and tension where others flopped.
Add in the general environment and the rookie coach making random decisions from nowhere and it was a horrible mix.
That said, it wouldn't surprise me at all if he was kept on.
