Vitesse Arnhem coach Peter Bosz doesn't know what to expect from his Chelsea loanees this season.

Bosz admits they'll miss Bertrand Traore, who was outstanding with Vitesse last term.

Isaiah Brown, Lewis Baker and Nathan have all moved to Arnhem this summer from Chelsea.

"They're young boys who are probably at the beginning of a beautiful career and have to play 34 games for the first time in a really tough league.

"The experience they will gain will be achieved with us," Bosz told De Telegraaf.
