Manchester United defender Wes Brown rates Tottenham and Manchester City are title threats.
Although Brown believes reigning champions Chelsea and Arsenal are United's two closest rivals for the title, he is refusing to rule out the possibility of a challenge from the likes of Manchester City or Tottenham.
"At the moment it looks like it'll be them (Arsenal and Chelsea), but you never know who else might come into it because there are some very good sides in the league," he told Inside United.
"The thing about Arsenal and Chelsea, though, is that they have great players and they know how to win."
