Noel Whelan has tipped Daniel Levy to investigate if Jose Mourinho’s ego is causing a rift in the Tottenham dressing room.

The former Premier League striker, speaking exclusively to Football Insider, insisted there were clear issues between the Portuguese boss and his squad after the “embarrassing” defeat to Dinamo Zagreb last week.

Spurs, who won the first leg 2-0, lost 3-0 in Croatia to see their Europa League hopes come crashing down.

However, the Lilywhites did bounce back to winning ways with a 2-0 victory over Aston Villa on Sunday.

Whelan suggested a lot of Tottenham’s issues stemmed from an unhappy dressing room.

As such, he tipped Levy to consider if Mourinho is still the man for the job.

“I think there’s going to be a lot of thinking to do for Daniel Levy at the end of the season,” Whelan told Football Insider assistant editor Russell Edge.

“It hasn’t been the most harmonious of times with Mourinho coming in. He’s not your arm-around-the-shoulder manager, he’s a bit tougher than that. He likes to be ‘the man’ and we know what his ego’s like.

“Sometimes that can get in the way and hinder a good relationship with players. I think it’s something that Daniel Levy needs to look at. There’s going to be changes at Tottenham.

“I think everyone let the club down with their performance against Dinamo (Zagreb). It’s embarrassing for Tottenham. This is going to stick in the throats of a lot of Tottenham fans. They’re going to wonder what is going on with their football club.

“Why are the players not producing? Why is Jose Mourinho not getting the best out of these players? They’ll be questions asked by Daniel levy as well. It’s very strange.

“You look at that squad, it’s fantastic, but why are they not clicking? Why has it been too many big players and big names left out the squads? There’s something not right there.”
