Pep Guardiola said Phil Foden has become a "world class" talent capable of deciding big games after the 23-year-old scored twice in Manchester City's 3-1 win over Manchester United on Sunday.

Marcus Rashford's wonder strike had fired United into a shock lead at the Etihad.

Erling Haaland was then guilty of a miss that will go down in Premier League folklore when he fired over an open goal just before half-time.
