Amad Diallo's development since Ruben Amorim took over at Manchester United shows why the Portuguese manager deserves time, despite an up and down start.

Ruben Amorim has challenged Amad Diallo to keep improving after the 22-year-old scored a dramatic 12-minute hat-trick to help Manchester United snatch a 3-1 victory over Premier League basement boys Southampton in a dramatic finish at Old Trafford.

Amad Diallo scored a dramatic hat-trick in the final 12 minutes as Manchester United came from behind to beat Southampton 3-1.

Amad embodies many of the traits Amorim wants from his team, and against Southampton he dug them out of another hole

Amad Diallo says he is happy to play anywhere Ruben Amorim wants him after scoring a hat-trick from wing-back as Manchester United beat Southampton. United were on course for another damaging, and deserved, defeat against a team bottom of the table, after a Manuel Ugarte own goal in the first half.

Ruben Amorim believes the remainder of Manchester United’s “hard” season will be a “rollercoaster” but that performances will improve with more training sessions. United defeated Southampton 3-1 on Thursday night thanks to Amad’s late hat-trick to move Amorim’s side up to 12th in the Premier League,
