Arsenal beat Middlesborough beat by two goals to nil and it was a good win for Arsenal and they managed to win without conceding a goal.
Arsene Wenger put out a strong line up as these days he cannot afford to put out a weakened squad because in these kind of cups the lower division teams always do well.
Manchester United beat Preston three goals to one and this was a good solid win for Manchester United. But to be fair I would have been very surprised if they had lost to Preston.
This win put Manchester into quarter-finals and takes them a step closer to winning a trophy under Luis Van Gaal.
