Chelsea have beat rival clubs to sign highly-rated Crewe Alexandra youngster George Nunn, reports the Metro.
The striker, who did not make a first-team appearance for the League Two side, was attracting interest from a number of Premier League teams after some impressive performances at youth level.
Tottenham had been monitoring his progress for some time but Chelsea have stolen the march and bagged the 16-year-old for around Â£300,000.
Nunn hit more than 20 goals at under-16 level and was promoted up to the U18 side where he scored a brace on his debut after coming off the bench.
The youngster rejected the offer of a contract from Crewe in order move to London to join the Blues where the striker will continue his development.
Chelsea have been accused of stockpiling young players giving the number that leave the club on loan each year but manager Antonio Conte is prepared to give youth a chance with Andreas Christensen and Ethan Ampadu both in the first-team picture.
The U18 side at Stamford Bridge have won the FA Youth Cup for the last four years and could be through to another final should they overcome Birmingham City in a two-leg semi-final at the beginning of April.
Nunn would be ineligible to play having already played for Crewe earlier in the tournament when they were knocked out by Colchester United in the third round.
Chelsea have yet to concede a goal in this seasonâ€™s FA Youth Cup and have dispatched both West Bromwich Albion and Tottenham on their way to the semi-final.
They put six past Fulham in the quarter-finals which all came during the second half where Martell Taylor-Crossdale scored a 20-minute treble.
Meanwhile, the first team sit in fifth-place in the Premier League table, five points behind Tottenham in the last Champions League place but are through to the FA Cup semi-finals where they meet Southampton.
The Blues will play Spurs in their next game on April 1.
