Tottenham are close to agreeing a new long-term contract with defender Dennis Cirkin, Football Insider can reveal.
The rising star left-back, 18, only signed his first professional deal last November at the age of 17.
A Tottenham source has told Football Insider that the club have secured a breakthrough in new deal talks with Cirkin and he is set to put pen to paper in the coming weeks.
It will tie the England youth international down beyond 2022.
Spurs have faith the teenager can eventually make the first-team grade and he has already been on the bench for a number of senior matches without yet being summoned for his debut.
The marquee signing of Sergio Reguilon from Real Madrid in a £28million deal has pushed Cirkin further down the pecking order.
But Ryan Sessegnon was loaned out for the season to German club Hoffenheim, and that means the Dublin-born youngster is effectively number three in the left-back pecking order behind Reguilon and Ben Davies.
Cirkin has begun this season in the Under-23s at Tottenham and played two of their four Premier League 2 matches.
He first made the first team squad for two matches earlier this year, FA Cup ties against Middlesbrough and Southampton.
The youngster was an unused substitute in both games, for which Jose Mourinho fielded strong teams as Spurs progressed to the fifth round of the competition.
He was making rapid strides before breaking down with a foot injury at the end of February, and bounced back to make the bench for a Premier League match for the first time, the 1-0 win over Everton in early July.
The teenager, a defender who can play at centre-back but is principally a left-back, was a regular for the Spurs Under-18s last season but made the quick leap to the senior squad after barely any Under-23s football.
