Jack Grealish scored his first goal in more than a year and James McAtee hit a second-half hat-trick as Manchester City surged to their biggest win since January 2019 to knock League Two Salford out of the FA Cup.

Grealish converted the 49th-minute spot-kick after he had been fouled, then exchanged a joke with routine penalty-taker Erling Haaland, who was on the bench after manager Pep Guardiola had chosen to leave out a number of big names for the third-round tie.
