Chelsea youngsters Isaiah Brown and Nathan have joined Vitesse on loan for the forthcoming season.
Brown joined the Blues two seasons ago from West Bromwich Albion and made his Premier League debut in a 3-0 defeat against his former side in May.
Meanwhile, Brazilian midfielder Nathan completed a move from Atletico Paranaense at the beginning of July.
A number of Chelsea players have moved to Vitesse on loan in recent seasons owing to a partnership between the two clubs.
