Marco van Ginkel has been included in Chelsea's revised Premier League squad for the rest of the 2018-19 campaign.
The Dutchman, who spent the last three seasons on loan at PSV Eindhoven, was prevented from joining the Eredivisie champions on a permanent deal after undergoing knee surgery in July.
Van Ginkel had an operation to reconstruct his anterior cruciate ligament and treat damage in his knee after suffering a series of knee problems early in his career.
But after Cesc Fabregas left the Blues to join Monaco in the January transfer window, Chelsea have decided to hand the 26-year-old a rare chance to ressurect his career at Stamford Bridge.
The Netherlands international is expected to return to training in March, although it remains to be seen whether he will be welcomed back into first-team action under Maurizio Sarri before the end of the season.
Van Ginkel enjoyed the best season of his career at PSV in 2017-18, scoring 16 goals in 33 appearances as Mark van Bommel's side cruised to their third title in four years.
He has made just four appearances for Chelsea since joining from Vitesse for £8 million in 2013, with loan spells at Stoke and AC Milan.
