Cesc Fabregas knows there's many of his former Arsenal fans seeing him in a Chelsea shirt. After Arsene Wenger failed to move for him during the summer, Fabregas signed for Chelsea in a £27m deal.
The midfielder told The Sun on Sunday: "I can understand some people at Arsenal are sad, some people are upset, some people are even angry.
"But changing clubs is part of the game and people must remember it was Arsenal who didn't take up the buy-back option for me.
"So what am I going to do - retire? No way!
"I have to look after myself. I had to make a decision."
