Alejandro Garnacho has not joined up with the Chelsea squad for pre-season as the Premier League club actively look to sell the winger.
Chelsea began pre-season training on Thursday for those members of the first-team squad not at the World Cup, but Garnacho was absent from the sessions at Cobham.
The situation is reflective of the 21-year-old's uncertain future at Stamford Bridge following an underwhelming season after his £40m move from Manchester United on a seven-year contract.
Chelsea value Garnacho in the £43m (50m Euros) region but will only entertain permanent offers, despite reports of loan interest from Serie A club Roma.
Premier League, European and clubs in Saudi Arabia are also believed to have shown an interest, with talks open and advancing with several parties. Manchester United are due 10% of any sale.
Garnacho scored just one Premier League goal in 24 matches, albeit with 10 appearances as a substitute, having struggled to start regularly under Enzo Maresca and then Liam Rosenior.
Any exit is part of a reshaping of Chelsea's squad this summer for new manager Xabi Alonso.
Chelsea have completed the signings of full-back Marco Palestra from Atalanta for £47m and winger Geovany Quenda from Sporting for £40m.
The club have also made two significant sales, with left-back Marc Cucurella joining Real Madrid for £52m and winger Tyrique George moving to Everton for a fee that could rise to £24m.
The Blues are targeting moves for a centre-back, with Crystal Palace's Maxence Lacroix among their targets, while Rayo Vallecano left-back Pep Chavarria is in talks to move to west London.
There are also a substantial number of outgoings expected, with Trevoh Chalobah's entourage exploring moves to Italian clubs Inter Milan and Como.
Chelsea finished 10th in the Premier League last season and are preparing for a pre-season tour of Australia and Asia in the next fortnight.
