Tottenham are advanced talks with Japhet Tanganga over agreeing a new contract after he rejected their initial offer, Football Insider understands.
The north Londoners have been in negotiations with the centre-back, 20, even before he seized his first-team opportunity so impressively.
A Tottenham source has told Football Insider that the club have held extensive talks with Tanganga and are confident an agreement is close.
This comes after he knocked back an offer from the club in November, back when he was still in the Under-23s and pushing for a first-team chance.
Tanganga has a contract that was originally due to expire this summer, but Spurs have already activated an option to extend it by 12 months to 2021.
The club have subsequently offered the England Under-20 international a long-term deal including a bumper pay rise.
Mourinho has claimed he would not have been playing Tanganga before the football suspension if Spurs had not already triggered the 12-month option in his deal.
The Portugese handed Tanganga a shock Premier League debut against Liverpool in January and he has started six of Tottenham’s last eight matches in the competition.
The versatile defender is predominantly a centre-back by trade but Mourinho has looked to ease him in mainly in the full-back positions, with five of his six league starts coming in the full-back positions.
Tanganga, who graduated from the Spurs youth ranks after first joining the club aged 11, has made 11 appearances in all competition for the first team.
