Paris Saint-Germain are ready to rival Manchester United and Barcelona for Tottenham Hotspur central defender Toby Alderweireld.

Alderweireld’s Spurs future is in doubt, as the club are yet to agree a new contract with the Belgian after talks stalled.

His current deal contains a one-year extension option, which is scheduled to activate in the summer of 2019 and would see him contracted to 2020.

But it also features a £25million release clause that could be activated in the summer of 2019, as long as a transfer was completed at least 14 days before the closure of the window.

That means Tottenham may have to listen to bids in the region of £40m for 29-year-old Alderweireld at the end of this season, which has alerted a host of clubs.

United and Barcelona have been following Alderwiereld’s situation for some time, particularly after Manchester City seemingly dropped out of the race by signing Aymeric Laporte.
