Chelsea have clinched a deal for AZ Alkmaar defender Justin de Haas, it has been reported.

AD says the 18 year-old will move to Chelsea at the end of the season when he comes off contract at AZ.

The defender moved to AZ in 2015 from KFC and is currently playing for the club's youth team.

De Haas has been capped for Holland at U17 level.

For their part, AZ insist there's been no approach from Chelsea about De Haas.
