Tottenham are on red alert as Manchester City struggle to tie emerging star Tosin Adarabioyo down to a new contract, according to a report.

Everton and Scottish Champions Celtic have also been credited with an interest in the England under-19 international, who has less than 12 months remaining on his contract at The Etihad.

The Daily Mail claim that City have tried to tie down Adarabioyo multiple times on a long-term deal but have so far failed because of the centre-back’s lack of assurances over first-team football.

New manager Pep Guardiola is said to be a big admirer of the 18-year-old emerging star but now faces a battle to keep him amid the interest from the elite trio.

The defender, who stands at 6ft 5in, was the only player in Guardiola’s squad to complete 180 minutes in City’s first two pre-season friendlies against German giants Borussia Dortmund and Bayern Munich.

City’s number 53 has made one appearance for the blue half of Manchester, playing in the 5-1 FA Cup loss to Chelsea last term.

According to Sky Sports Italy journalist Gianluca Di MarzioTottenham are set to lose Federico Fazio to Roma, and could be tempted to bring in Adarabioyo as depth. Spurs have just three senior centre-backs on their books in Jan Vertonghen, Kevin Wimmer and Toby Alderweireld.

SkySports reported that Everton’s £10million bid was rejected for Swansea captain Ashley Williams, so they could make a move with City closing in on a move for John Stones.

Scottish Champions Celtic are also keen, with Rodgers using a three-centre-back system and needing more depth than those playing with two centre-backs.

In other Tottenham transfer news, Spurs aren’t sure on this Premier League champion despite making a bid.
