Gary Neville says Tottenham has the firepower to win the Premier League, but believes their defence will ultimately cost them.
Spurs are second heading into the international break after a slim 1-0 victory over West Bromwich Albion.
And Neville believes it would make a great story for Mourinho to end Tottenham's 59-year wait for a top-flight title.
"I said a couple weeks ago on Monday Night Football that Spurs couldn't win the league, and I still don't think they can," he told The Gary Neville Podcast.
"But I do agree with Jamie Carragher that it would be the most outstanding story to see Jose Mourinho win the Premier League with Tottenham.
"It would be something that would alarm Chelsea fans, Manchester United fans and Arsenal fans. It would be one of the great stories, because Tottenham don't win leagues!
"He's got the forward players to do it. You think of the strike force and the goal - it's incredible."
