Football: Manchester United knock Arsenal out of FA Cup with 3-1 win

Alexis Sanchez scored the first goal against his former club as Manchester United beat hosts Arsenal 3-1 in the fourth round of the FA Cup on Friday. Sanchez opened the scoring in the 31st minute and team-mate Jesse Lingard doubled the advantage just over two minutes later - Romelu Lukaku with a hand in both strikes. Pierre-Emerick Aubameyang tapped in a simple goal from an Aaron Ramsey pass just before half-time to keep the 'Gunners' in the game. However, Anthony Martial would seal the win after coming off the substitutes' bench, slotting home a rebound after Paul Pogba had forced a save from Petr Cech. The match ended on a sour note, with a coin being thrown from the stands following a fracas between the two sets of players.
