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.

For 80 minutes, all the problems United had suffered during a run of four straight defeats during December resurfaced as a Saints side with only one win all season created the better chances and deservedly led through a Manuel Ugarte own goal late in the first half.
