Arsenal midfielder Cesc Fabregas says the spirit inside the dressing room is the key to their success this season.

Fabregas, 20, said: "The key to our success is the bond that exists in the dressing room. Our unity is fundamental to achieve good results and play good football.

"We are all committed to each other and that is very important. Only a team as compact as this can go 18 games unbeaten."
