Manchester United manager Jose Mourinho says the enjoyable win over Liverpool on Saturday could count for nothing if his team do not follow it up with success in two huge cup ties this week.
The experienced boss is fully aware of the nature of the modern game and has, once again, emphasised the importance of the knockout ties - starting with the delicately poised UEFA Champions League encounter with Sevilla.
After a goalless draw in Spain in the first leg, the Reds will be wary of conceding an away goal against Vincenzo Montella's side and need the Old Trafford crowd as noisy as it was for the grudge clash with the Merseysiders.
