Manchester City and Manchester United will battle to sign £40million Napoli centre-back Kim Min-jae — dubbed ‘The Monster’, according to The Sun.

The South Korean, 26, is also attracting interest from Premier League rivals Liverpool and Tottenham Hotspur.

The report adds: “City boss Pep Guardiola is an admirer of Kim, who only moved to Napoli from Fenerbahce last summer for £15m.

“Strong, aggressive Kim is one of Serie A’s hottest stars following a stunning season and has a fairly low £40m release clause.

“The Italians are keen to offer him a new deal but he is believed to fancy a move to England.”
