Hull City midfielder Ryan Mason believes that Tottenham can challenge Manchester clubs for the league title if they can sort out their home form.
Spurs are yet to register a league win at their new home Wembley Stadium this season, but they sit in the third spot, just five points behind the two Manchester sides.
He told Sky Sports: "Vincent Kompany is a massive one for [Manchester City].
"If they can get him back [fit] and playing 25 games until the end of the season then I think they'll be up there.
"But I still think [Manchester] United - and I believe Tottenham [can] as well.
"I look at their teams, I look at their squads, I think if Tottenham can sort their home form out then I think they'll win it.
"But [Jose] Mourinho has done it before hasn't he? And if you look at Mourinho and United now and you think 'this is a United team'."
