Chelsea have announced Izzy Brown and Nathan will join Vitesse on loan for the 2015-16 campaign, while Andreas Christensen is to spend the season with Borussia Monchengladbach.
Versatile forward Brown made his senior debut at the back end of last season, while attacking midfielder Nathan is a new arrival from Atletico Paranaense.
And both players will now become the latest Chelsea youngsters to spend time with Eredivisie side Vitesse – as part of a continuing partnership between the two clubs.
Another teenager, Christensen, has agreed a season-long loan move to Gladbach.
The Danish defender also made his senior bow for Chelsea last term, in addition to gaining international recognition.
