Chelsea midfielder Marco van Ginkel will not rejoin PSV Eindhoven on loan due to a persistent knee injury.
Van Ginkel, 23, joined the Dutch giants on loan last season following a lacklustre first half of the season on loan at Stoke City. The Dutchman enjoyed a hugely impressive campaign back in his homeland, scoring eight goals as he helped the club take back the Eredivisie title.
The Dutch champions were hopeful of bringing the player back on another loan deal, with a permanent transfer not an option.
In July, the club's technical director Marcel Brands told Voetbal International they were still waiting to learn of Chelsea's plans for the player. "It is of course important that the player has clearly indicated that he really wants to stay another year with PSV."
Van Ginkel did not feature for Chelsea during their preseason campaign and the midfielder has now revealed a knee problem has dashed his hopes of returning to PSV for another season.
He wrote on Instagram: "Because of physical problems, it unfortunately is not possible for me to join PSV again. I had a really good time in Eindhoven and winning the Dutch championship felt absolutely amazing. I want to thank all supporters, players and staff members of PSV and maybe we meet again soon."
Van Ginkel joined the Blues from Vitesse Arnhem in the summer of 2013 but just months on from his arrival he suffered a season-ending knee injury in a League Cup tie against Swindon Town.
During the 2014-15 season he joined Milan on another loan deal but struggled to make an impact at the Rossoneri, suffering a string of ankle problems during his spell in Italy.
Van Ginkel was one of 29 players to leave Chelsea on loan last season but is now likely to remain at the club to complete his rehabilitation at the club's training facilities at Cobham.
