Jack Clarke is being tracked by a growing number of Premier League
clubs as Leeds United look to tie down the promising teenager on a new long-term deal.
The 18-year-old winger has progressed through the vaunted academy at Elland Road and taken the Championship by storm in recent weeks.
He made his debut against Brentford in October before a number of eye-catching substitute appearances marked him out as a special talent.
Clarke made his first league start for Marcelo Bielsa's men during Friday's 2-0 home win over Derby which strengthened Leeds' position at the summit.
The boyhood Leeds fan from York created goals for Kemar Roofe and Jack Harrison in a man-of-the-match display in front of watching England manager Gareth Southgate and Under-21s boss Aidy Boothroyd.
Although uncapped at any youth level, Clarke's dramatic emergence prompted a visit from Southgate, a noted advocate of young talent, and the teenager seems destined for the top.
Clarke's proud parents and sister were also among a bumper 34,668 crowd and starting a league match for the first time marked the realisation of a childhood dream for the academy product.
One source said: 'When Jack came on at half-time against Reading in November, he was up against Chris Gunter, Wales' most-capped player, but he had the beating of him quite easily.
'At Aston Villa in December, he came on and a pass was drilled at him and he had a bad first touch and the ball went out of play.
'A lot of players would probably then go into their shell or play safe but what did Jack do with his second touch?
'He collected a pass from Pablo Hernandez, took on Ahmed Elmohamady and curled the ball into the net.
'Jack only turned 18 in November but he's thriving at Leeds because they have the best manager in the Championship in Marcelo Bielsa.
'If you're good enough and willing to work hard and listen, Bielsa will put you in there.
'On Friday against Derby, Leeds had a handful of academy players on their bench and the likes of Jamie Shackleton and Leif Davis are two more very promising teenagers.
'But Jack is the cream of the crop and nothing fazes him. He's got no fear and it doesn't matter who he's up against - he just wants to keep getting the ball and attacking.
'Give him an opportunity and he will take on his opposing full-back, no problem.
'Not only that, he's a great lad off the field and the first-team lads at Leeds love him. He has been at the club from a very young age, has really good parents and is a very grounded kid.'
Clarke has 18 months remaining on his existing deal at Elland Road but Leeds are yet to offer him new, vastly-improved terms in accordance with his soaring reputation.
Pep Guardiola is a known admirer of the teenage sensation, but it is understood that Clarke is keen to stay at Elland Road and continue progressing under Bielsa.
Harrison, on a season-long loan from Manchester City, said of Clarke: 'Jack's a brilliant young player and he only gets better every time he plays.
'He is growing in confidence and that's massive as a player.
'It's almost as if nothing can stop him and you saw against Derby what he's capable of. I'm sure he will keep on improving.'
Leeds are poised to end their search for a goalkeeper by signing Real Madrid's Kiko Casilla and also remain in the hunt for another winger and No 10.
