Tottenham risk losing Sergio Reguilon back to former club Real Madrid.

Reguilon is reportedly being lined up for a Real Madrid return next summer - thanks to the buy-back clause in his Tottenham contract.

The clause means Spurs have to accept an offer for their new left-back from the Spanish club - if it hits a pre-agreed price.

AS says the change in heart has come in part as the club come to terms with the ageing Marcelo.

The 32-year-old has been a mainstay at the club since 2007 but his recent form has caused alarm that an 'unstoppable' decline is beginning.
