Chelsea’s new manager Mauricio Pochettino has said that a customised training regime will be used to unlock the full potential of Enzo Fernandez, Mykhailo Mudryk and Raheem Sterling.
The former PSG manager will take charge after Chelsea finished 12th in the Premier League last season.
"Different players arrived in different circumstances but of course now is an opportunity," Pochettino told Chelsea's website, outlining his plans for the team ahead of the pre-season.
Chelsea will begin pre-season in the United States with a match against National League champions Wrexham on July 19.
"I hope we can help them to achieve their best level, a higher level, and try to perform for Chelsea in the way that people expect," he said.
"Now is a new start, a fresh start, and I think they need to show their real quality. But we need to create this platform for them to feel comfortable and breathing space for them to perform and improve."
Pochettino said that Fernandez, who was named the best youngster at last year's football World Cup after helping Argentina clinch the title, needed rest after a tough schedule.
"The Premier League is a really tough competition and he changes everything – culture, language, everything – and it is always difficult to adapt," Pochettino said.
Pochettino also stated that Mudryk's "mindset and everything is different" than Fernandez's, which is why he will look to spend more time with the 22-year-old.
The experienced Sterling has not been able to live up to expectations after leaving Manchester City, where he won 10 major trophies, having scored just nine goals in 38 appearances for Chelsea.
"It's not always to blame the player... We need to see us and see what is going on and why they are not performing in the way that we expect and then, of course, when all is clear, we cannot give excuses to them to not perform." Pochettino added.
