- Cesc Fabregas reveals he still feels guilty about Mourinho's sack at Chelsea
- The Spanish midfielder admits the players forgot how to play football and let the manager down
- Jose Mourinho was sacked six months after winning the Premier League title with Chelsea
Cesc Fabregas was brought back to England for his second stint in the Premier League when Jose Mourinho paid £27 million Barcelona for his services to bring him to Chelsea in the summer 2014.
The Spaniard won his first Premier League title under Jose Mourinho in 2015/2016 season under Jose Mourinho.
However the following season was a disaster for Chelsea as they offered one of the worst title defence English football has ever seen, which saw Mourinho being booted from Chelsea six months after winning the title.
The fans turned on some players for letting the manager, Fabregas was one of the players turn on with the fans calling him a "rat".
Cesc Fabregas revealed he still has sleepless nights about Jose Mourinho's sacking from Chelsea.
Fabregas, in an interview with the BBC's Premier League show, said: "I still wonder myself because it was such a shame.
"You go to bed sometimes and you think of many things and sometimes you cannot sleep.
"Still sometimes it bothers me because I could look from the outside as a fan and think, ‘these guys are not even trying’. But we just forgot to play football.
"You felt that those six months we were nowhere close to what we really were just a few months before. But it happened and I felt bad for it.
"We still talk today. He is probably the manager that I have had the best feeling and connection for, apart from Arsene (Wenger), the one I have the most contact with is Jose."
Jose Mourinho returns to Chelsea for the second time since getting sacked by the blues in the league with his Manchester United team, last season Mourinho suffered a humilating 4-0 defeat and will hope last season's result doesn't repeat itself.
