Jose Mourinho believes that Heung-min Son could be playing for Chelsea and considers him as one of the best players in the world. Heung-min Son joined Spurs for €30 million back in 2015 and has become a fan favourite in north London. Despite being named Spurs captain last summer, his contract at the Tottenham Hotspur Stadium is due to expire in 2025, meaning an exit of some kind is plausible within the next 12 months.
