Chelsea have completed a deal to sign Denmark youth international Andreas Christensen from Brondby on a free transfer.
Following interest from Premier League rivals Arsenal and Manchester City, as well as German giants Bayern Munich, the Blues have reportedly won the race.
The 6ft centre-back has already been capped at Under-17 level by his country, and says the Stamford Bridge club are willing to invest in his future.
"I have chosen Chelsea because they play the kind of football I like,” Christensen told Ekstra Bladet.
"At the same time, they have the best plan for my future in football."
Christensen follows the January transfer window additions of Gary Cahill from Bolton Wanderers and Kevin De Bruyne from Genk.
The 15-year-old, like De Bruyne, will join the Premier League side in the summer.
Andre Villas-Boas has also been boosted with the news that midfield pair John Obi Mikel and Frank Lampard have returned to training following respective hamstring and calf problems.
Nigerian star Mikel hasn't featured since December's draw with Tottenham Hotspur, while Lampard has missed the last three games, including the weekend draw with Manchester United.
