Pep Guardiola says he expects Manchester United to be serious challengers for this season’s Premier League title once they complete the signing of Harry Maguire from Leicester City for £85m, a world-record fee for a defender.

Guardiola, who was speaking after his side edged past Liverpool on penalties in the Community Shield final, also revealed his club were interested in Maguire, admitting 'but we couldn't afford him'.
