Chelsea have announced that Izzy Brown and Nathan will join Vitesse on loan for the 2015-16 season.
Versatile forward Brown made his senior debut for the Blues at the end of last season, while attacking midfielder Nathan joined the club from Atletico Paranaense on July 1.
Both players will now head to Eredivisie, becoming the latest Chelsea youngsters to do so as part of a continuing partnership between the two clubs.
Brown joined Chelsea from West Brom, with the Baggies complaining about the transfer after losing one of their finest academy products.
