Marco van Ginkel has signed a one-year contract extension with Chelsea before heading back to PSV for a second loan spell.
Van Ginkel has made just one appearance for the Blues this season, in the Checkatrade Trophy, but has penned a new deal that ties him to Stamford Bridge until 2019.
The Netherlands international also spent the latter half of last season at the Philips Stadion, scoring eight goals in 13 games to help propel Philip Cocu's side to the Eredivisie title.
Having fully recovered from a knee operation that prevented him from moving to PSV earlier in the campaign, Van Ginkel hopes to establish himself once again in a midfield set to be swollen by Andres Guardado and Jorrit Hendrix's imminent returns from injury.
