Ruben Loftus-Cheek has hit out at Chelsea for the lack of opportunities they give to young players that come through their academy.
The 22-year-old made his debut in 2014 but has made just 32 appearances for the club.
He has barely featured since Antonio Conte became head coach in 2016 and spent last season on loan at Crystal Palace.
The midfielder's performances earned him a call-up to England's World Cup squad.
Despite his development, it is not clear whether Chelsea see him as part of their plans for the coming campaign.
Asked about his experience of life at Stamford Bridge, Loftus-Cheek said: "It's been so difficult to go from playing every game then get to the seniors and not be given a chance.
"It's really difficult mentally, there's only so long you just enjoy training with top players.
"From a year ago, I've improved so much from playing. A game situation is completely different.
"It's hard to compare the faith of Gareth Southgate and Roy Hodgson and my lack of chances at Chelsea because it's such a big club - managers are under pressure and maybe don't want to take a chance on a young player.
"I don't understand what's going on behind the scenes fully, but Chelsea's a massive club and I understand why chances don't come so often".
