PSG defender Alex still regards sacked Chelsea manager Andre Villas-Boas as a great coach.
Alex took no joy from seeing AVB's demise on Sunday.
He said of Villas-Boas' departure: "When the results do not show up, the one who pays is the coach.
He added: "At Chelsea it had already happened several times, the exit of a manager in the middle of the season.
"It is a big club, where there is enormous pressure to win the Champions League. You cannot say that this pressure affects the players every day, but perhaps it affects the work of coaches.
"And do not forget that the Champions League is a competition that is difficult to win.
"This situation was being talked about for a while, even because of Andre's behaviour." "But Andre is a coach with great quality, as I saw day to day in how he worked on every single detail."
