Noel Whelan believes there has been a ‘Massive’ falling out between Jose Mourinho and Gareth Bale at Tottenham after Thursday’s defeat to Chelsea.

The former Leeds United striker, speaking exclusively to Football Insider, suggested something had gone “massively wrong” between the Welsh winger and the Portuguese boss in the build-up to the London derby.

Bale was left as an unused substitute against the Blues as Mourinho chose to bring on the likes of Erik Lamela and Lucas Moura in the 1-0 loss.

As quoted by the Guardian, the Spurs boss refused to reveal why he chose not to bring the Real Madrid loanee on and insisted he, Bale and everybody is “doing their best”.

The Welsh star has struggled for form since his return to north London and has just two Premier League starts under his belt this season.

Whelan believes something has gone on between player and manager and suggested Bale will not want to turn his temporary move permanent at the end of the season.

Whelan told Football Insider assistant editor: “There’s a problem there, there is an issue, there’s an underlying issue there between manager and player again, very much like Dele Alli.

“I’ve got no idea what’s going on, there’s a trust issue, there’s a battle of egos out there somehow, that’s not working. Why has Gareth Bale been brought in if he’s not going to be used?

“He was wanted for years and now they managed to get him and they don’t even put him on in a massive game to get back into a game. Now, even Real Madrid did that and Tottenham aren’t. 

“There’s something massive going wrong there between the connection of manager and player and we don’t know what it is, but there’s a huge issue, there’s a huge issue there. I can’t see him being there at the club come the end of the season.

“I do not think they’ll take up that option of buying him and I’m pretty sure Gareth Bale won’t take up the option of wanting to stay if the season carries on this way for him.”
