Amad Diallo has struck a 90th-minute winner as Manchester United staged a stunning late comeback to beat Manchester City 2-1 in the Premier League.

Amad Diallo inspired Manchester United to a 2-1 comeback derby win at the death as Ruben Amorim piled more misery on Pep Guardiola’s malfunctioning Manchester City. All eyes were on the Etihad Stadium as the Portuguese led the Red Devils across town for the first time to take on a side that he last month stunned in his penultimate match as Sporting Lisbon manager.
