Chelsea defeated 10-man Manchester United 1-0 in the quarter-finals of the Emirates FA Cup at Stamford Bridge on Monday night.
Super Eagles forward Victor Moses featured from the start before going off for Kurt Zouma in the dying minutes of the game.
Following the sending off of Herrera, Chelsea were all over United and almost took the lead on 40 minutes but Moses’ powerful shot from range sailed just over the bar.
Man United started the stronger and were almost rewarded for their good start on 12 minutes through Henrikh Mkhitaryan but his low left-foot strike rolled narrowly off target.
Chelsea began to grow in the game and went very close on 16 minutes only for Eden Hazard’s low strike to be tipped by David De Gea away for a corner.
De Gea was called to action again from the resultant corner as he got down quickly to palm Gary Cahill’s shot away from nestling into the bottom corner
