Kalas and Van Aanholt seal loan switch
Chelsea duo Tamas Kalas and Patrick van Aanholt have returned to Eredivisie side Vitesse Arnhem on season-long loan deals.
The duo had spent time at Vitesse last season and will now further their development during the 2012-13 campaign.
Kalas, who made 29 appearances for Vitesse during his previous spell, had signed a new contract at Stamford Bridge until 2017 before making the move.
Van Aanholt, 19, had spent time on loan at Wigan before joining Vitesse last season but managed nine appearances for the Dutch side.
