Five years ago, Son Heung-min revealed how Mauricio Pochettino helped him become one of the Premier League's most feared wingers. With Mykhailo Mudryk yet to truly establish himself at Stamford Bridge, the newly-appointed Chelsea manager can rework his magic and help the Ukrainian fulfil his potential.
Despite having shown glimpses of magic, Mudryk has struggled to impress since arriving in the English top flight. The 22-year-old winger was first linked with a move to Arsenal, only for the Blues to swoop in and hijack negotiations at the eleventh hour.
Initial talks between the Gunners and Shakhtar Donetsk were thought to have progressed well before a bid was tabled. Arsenal remained in contact with the Ukrainian side and, at one stage, they were confident that they would win the race for his signature.
