Chelsea midfielder John Obi-Mikel has claimed that former manager Andre Villas-Boas failed to communicate with players during his time in charge at the club.
Villas-Boas was sacked by Chelsea in March and Mikel insists that the players did not have a good relationship with the Portuguese coach.
The Nigerian said: "The communication was not right. You think you have played well in a game and the manager then leaves you out. You don't know the reason why. Things like this went on through everyone's head and not just mine.
"Nobody knew what was happening. When you have something like that in your mind, you don't know what to do. You come into training and think, 'Should I train well, because I don't know if I'm going to be playing at the weekend?'
"Things like that just went on and on."
Chelsea are currently sixth in the Premier League with just Sunday's match against Blackburn Rovers left to play.
