Arsenal goalkeeper Petr Cech rates Manchester United as title contenders.
Cech played for United boss Jose Mourinho at Chelsea.
He told talkSPORT: “I still count them as a title contender, even if they are a little behind now, because it is a long-term competition and I know the manager very well.
“He will do everything to make sure, if they can, that they can close the gap and as their opponent we need to make sure we don't give them the chance.
“He spent a lot of money [in the summer]. They bought the players he wanted so it is how well they find a way to compete and put it on the pitch."
