Alan Hutton claims that “something is going on” at Tottenham for manager Jose Mourinho to omit Toby Alderweireld and Jan Vertonghen from his starting XI .

The former Spurs and Scotland defender, speaking exclusively to Football Insider assistant editor Russell Edge, ripped into the quartet after their “schoolboy” display at Bramall Lane.

Eric Dier, Serge Aurier and Ben Davies all kept their places for Monday’s win over Everton, with Davinson Sanchez dropping out for Toby Alderweireld.

However, Hutton believes that all four deserved to be axed after their dire display in the 3-1 defeat to the Blades and insists that new recruits are needed this summer.

Discussing Tottenham’s defensive options, Hutton told Football Insider: “I think Alderweireld and Vertonghen, when they’re on top of their game, they’re a world-class partnership. It just feels something’s gone on there for them not to be playing. 

“Tottenham looked frail, especially the Sheffield United game, they looked really bad. It’s obvious where they need to strengthen and that’s the backline in my opinion. It was really disappointing.

“I just think the defending in the Sheffield United game, even when I think about it now, it’s schoolboy stuff. It’s just covering, matching your runners, stopping one-twos – it’s simple, the basics of being a defender just weren’t there.

“He could have changed the full back-four against Everton, Sanchez got pulled out of the firing line.” 

Monday was Alderweireld’s first start since the Premier League restart after spending the first three games as an unused substitute.

Jan Vertonghen was joined by the axed Sanchez and young Dennis Cirkin as Mourinho’s defensive options on the bench against Everton.
