Toby Alderweireld ends doubts over his Tottenham future by signing new contract

But the arrival of Jose Mourinho has brought about a change and the Belgium international will now stay until 2023.

A club statement read: "We are delighted to announce that Toby Alderweireld has signed a new contract with the club until 2023."

Despite his contract stalemate Alderweireld, who followed Pochettino to Spurs having been on loan at Southampton in 2015, has been a mainstay of the defence in recent times, making 50 appearances last season.

The club exercised an extension in his contract last term which also triggered a £25million release clause, but only Roma were interested in the centre-back and made a much smaller bid in the summer.

Alderweireld, who has a young child and a second on the way, has now decided to stay in London and has committed his long-term future to the club.

He told Spurs TV: "I'm very, very happy. I'm honoured to play for this club and I'm a small piece of getting to the next level in a couple of seasons. I think this is just the beginning of something big and something very exciting.

"I couldn't see myself playing for another team. I think the club likes me, I love the club, the fans, the stadium, everything. It's like I'm living some sort of dream."

Alderweireld's Belgium team-mate Jan Vertonghen is also out of contract in the summer and can discuss terms with European clubs in the new year, though has expressed a desire to sign a new deal.

Christian Eriksen has reportedly told Mourinho he will not sign a new contract and looks set to leave on a free in the summer, unless Spurs can sell him in January.
