Cesc Fabregas admits he is losing sleep over Chelsea's shocking start to the season

The midfielder also said his “life is not happy” following the unexpected downturn suffered by Jose Mourinho’s side, who have already lost seven Premier League games this season after winning the title at a canter last term.

Fabregas tasted success as Spain beat England in Alicante on Friday night, but his thoughts quickly turned back to club matters and the malaise afflicting Chelsea.

He threw his support behind Mourinho and revealed the plight had left him unable to sleep.

"Sometimes when I am at home, in bed, I wonder,” said Fabregas. “You have your own thoughts and the manager will have his thoughts about what is going on and it is all about talking about things and putting this right altogether.

"Yes [it keeps me awake at night] when things don’t go right, Football is my life. It is everything to me. My family keep me happy sometimes, but when football does not go well, my life is not happy. I try to fix it and try to put it right.

"We are used to always being at the top. This season is being f*****. The results have not done justice to what we do on the pitch.

"We are doing things better, but we’ve had no luck. We have to start winning now.”

It is the adjustment to being marooned in uncharted territory that Chelsea, currently languishing in 16th place, just three points above the relegation zone, are finding difficult.

They host Norwich on Saturday in their next fixture and Fabregas stressed the importance of launching a mini-revival ahead of the congested Christmas period.

"It has been difficult,” said Fabregas. “Really difficult, obviously. We are not in the best moment at the club and we want to lift ourselves up and we want to start playing better than we have been doing. It has been difficult as we don’t like to be losing.

"For me and the manager and some other players, we have always been lucky enough to play for big teams. Always trying to get to the top and always be fighting for things.

"In the Champions League, we are still there and the FA Cup has not even started yet so it is all about the League, trying to put the good performances in week-in, week-out and trying to be as high as we can around Christmas because then, it will be a very, very tough time.

"I cannot support him [Mourinho] even more than I am doing. I am always saying he deserves it, 100 per cent. We are not playing well but that does not mean we are not in favour of the manager or something like that.

"We want to win for Chelsea – that is the first thing. We want the club to be at the top and someone like Mourinho who is having difficult times and the players, then you have to support each other and give our best.

"When you know things are not going your way, you have to do even more. When things go well, you touch the ball with any part of your body, you are not looking and it goes in. We need to put extra work in.”

Fabregas provided the chip which Spain right-back Mario acrobatically volleyed beyond Joe Hart for the opening goal in Alicante before Santi Cazorla sealed the 2-0 victory.

Yet he had consoling words for an England team he believes are in transition and need to be more ruthless with the chances they create on the counter-attack.

"They are a young team, same as us, changing a little bit as the Gerrards and Lampards have gone,” he said. “It is the same for us with Xavi, Alonso and David Villa.

"They will compete very well in the Euros, that is for sure. If you ask me now, right now, if they are one of the favourites, I would say yes.

"But, of course, they will need to score the chances they create because counter-attacking, they are one of the best sides. And when they get chances with Sterling, Kane and Rooney, Lallana, they have good players but they have to take their chances.

"We cannot play like that because we don’t have the players. We play in another style but, 100 per cent, a counter-attacking side can win the Euros. But you have to be a special team.”

Fabregas paid his respects to the victims of Friday’s terror attacks in Paris by laying the ball he received for his man-of-the-match performance against England outside the French Embassy in Madrid .

Fabregas was playing for Spain at Wembley when news of the events in the French capital broke.

"It was a strange situation. We finished the game, we were congratulating each other, and suddenly we stood,” he said.

"We were talking, commenting on the news that was coming in. I didn’t want to believe it, and we did not know what to say.

"They are misfortunes that should not and cannot happen in today’s world.”
