The ex-Spain worldwide went on to feature in 303 games across all competitions for the Gunners, becoming a favourite among supporters for his exceptional passing range, fierce passion and combative style in the middle of the park. But despite spending nine years at the club - the longest he has stayed in any club - Fabregas lifted only one trophy with Arsenal before moving to Barcelona.
'Once I decide to leave (Barcelona), Arsenal will have the first option of any other club and I can not speak to any other club for one week to see if Arsenal want me or not, ' Fabregas told the Arsecast podcast.
'I was the captain, I always felt so much pressure on myself, ' he told Arseblog.
"To be honest, after I left the room with Mourinho I said, 'thats it, I dont need to talk to anyone else, Im going to Chelsea.' What he told me, the team he wanted to make, what he thought of me, how he wanted me to play, this is what I wanted".
'I used to suffer, I used to spend sleepless nights suffering.
"Especially in the last 2 or 3 years, I really felt Robin and also Samir were the only gamers - it's not an egotistic point to claim, it's just how I really felt during that time - were the gamers that went to my degree psychologically and also practically".
Fabregas left Arsenal for Barcelona in 2011 after eight successful seasons, but struggled to establish himself back home with Xavi, Andrés Iniesta and Sergio Busquets ahead of him in the pecking order.
I was drained mentally, physically, in my soul - knowing I'm giving everything, knowing a couple of signings that I knew could have happened and the club didn't make the effort.
"Seeing some behaviors from specific gamers or something similar to this made me feel I wished to inspect another thing".
Fabregas has three assists this season for Monaco, averaging 1.3 key passes and 40.8 passes per game.
The match was also Thierry Henry's last game for Arsenal as he moved to Barcelona the following season where he won the La Liga title and also the Champions League he failed to win in London.
