Chelsea will be concerned about being unable to offload Mykhailo Mudryk permanently following his loan move to Tottenham Hotspur.
That is according to former Everton chief executive Keith Wyness, speaking exclusively to Football Insider, who believes that the winger must reach double-digits in goals for Tottenham to trigger his £75million buy clause.
Mudryk joined Roberto De Zerbi's side on Deadline Day, as did teammate Tosin Adarabioyo, but only on a season-long loan from Stamford Bridge.
And despite many fans excited to see what he can bring to North London, the Ukrainian international has already suffered a major setback.
After making his debut off the bench against Nottingham Forest, it has been revealed that Mudryk is likely to miss the next two months with an ankle injury.
With a huge price tag to live up to this season, it could not have come at a worse time for the Chelsea loanee, and those in West London will be concerned.
Mykailo Mydruk must be worth '£100m' to earn move
Everton's former chief Wyness – who served as CEO at Goodison Park between 2004 and 2009 and now runs a football consultancy advising elite clubs – has raised concerns over Chelsea's hopes of offloading their big-money player.
Speaking on the latest edition of Football Insider's Inside Track podcast, Wyness believes that Mudryk needs to be a "superstar" to live up to his price tag.
"It's Chelsea who are the ones who are sweating on his performances right now because they're the ones that could be stuck with a very valuable asset," he said.
"And Mudryk really has got, if he's going to try and salvage his career, to really outperform. He's doing it in an environment that's already under a little bit of pressure.
"Coming into that environment isn't the same as coming into a successful winning team. It's coming into a bit of a hot house. Let's just see how he goes.
"But all this is a chance for him to audition and to prove his worth. He's going to have to do a hell of a lot to make it worth £75m. He's going to have to outperform that.
"He's going to have to be worth £100m. He's going have to be a superstar to make that work. And I don't see that happening, to be honest.
"So I would expect him to be back at Chelsea in the not-too-distant future. I don't think this is going to work out with a happy ending, in my view."
