Arsenal legend and coach Robert Pires believes the title race will be over if Chelsea beat Arsenal on Saturday.
“It will be difficult after the last game that we lost against Watford – it was terrible,” Pires told FourFourTwo.
“We have another chance next Saturday. For me this is a big final for the Premier League. If Chelsea beat Arsenal, I think the Premier League is done.
“Chelsea play very well, they are a very good team, very compact. They have the Italian philosophy, they play together.
“They are maybe stronger but we need to believe in this opportunity. I think this is the last opportunity.”
