Spurs currently have several star players in their team and there is a concern that they could be prized away in the near future.
The Manchester Evening News report that Manchester United are keeping tabs on defender Alderweireld, who is an integral parts of Mauricio Pocehttino’s backline.
It is understood the 28-year-old centre-back is stalling over a new contract with the north London club, which his currently deal set to expire in 2019.
Alderweireld’s recent absence in the Champions League raised fresh speculation about his future, but he is being eased back from his long-term injury.
Meanwhile, 21-year-old Alli is regarded as one of the best youngsters in world football and has become a star.
The attacking midfielder has been in great form this campaign during his 35 appearances, scoring nine goals and supplying 12 assists.
BT pundit Jenas feels that if Spurs are to sanction the exit of any players in the summer ahead of their move to a new ground, Alderweireld and Alli are prime candidates to be moved on for big money.
“If I was going to guess, I would say Dele Alli might go [in the summer]. If the new stadium does exert some financial pressures on the cub, Dele is the kind of player that Spurs could replace,” Jenas wrote for GQ magazine.
“Dele is without doubt a brilliant player and I am sure he will go on and play for another top team, but in the area he plays in he is replaceable.”
“Another player who looks like he might leave is Toby Alderweireld. He seems like he wants to move on and there will certainly be no shortage of suitors for him.”
Spurs’ brilliant display in the 2-2 draw away to Juventus on Tuesday night showed how far they have progressed under Pochettino. However, they can’t afford to rip out the nucleus from their side if they want to go on to become a side that wins trophies. Alderweireld and Alli are certainly pivotal to the immediate future of Spurs and are a part of their best XI. The north London club would find it very, very difficult to find a replacement for defender Alderweireld given his all round talent. Jenas has suggested that Alli could be replaced by Spurs, but at just 21 he still has so much potential to improve as a player.
