Former Spurs midfielder O’Hara slammed Tottenham’s pre-season and said their transfer business has been embarrassing.
O’Hara told Grosvernor Sport: “If I’m Harry Kane, I’m leaving.
“I would have looked at pre-season, where Spurs have only played two games so far and seen that it’s a shambles.
“I’d see that the club haven’t attracted any top-quality players and say, ‘Do you know what? I’m going to go to Bayern Munich’.
“It’s got to the point now where enough is enough – if Spurs aren’t going to compete, then he needs to leave.
“I just think Spurs have fallen away from the likes of Arsenal and Manchester United.
“The only saving grace that the club has is that they still have Kane and Heung-min Son.
“But if you look at the rest of the team, it’s no better than West Ham.
“Arsenal, Manchester United, Chelsea and even Aston Villa are all going to be better than them next season.

“They’re attracting top players, but Spurs are not – some of the players that they’ve signed are just embarrassing really.”
O’Hara also doesn’t believe Richarlison would compensate the loss of Kane.
He said: “Richarlison is not the answer.
“As much as I think he can be a good player, he had a bang average season last year– he’s just not the answer.”
He’s not optimistic about seeing a ‘different’ Tottenham this season.
He said: “I’m not looking at it and thinking, ‘they’re going to have an amazing season,’ because they’re not – they’re going to be bang average.
“The wheels have fallen off Tottenham in my opinion.”
