The Reds will have a second chance to reach the semi-finals, with a forthcoming replay at Stamford Bridge where United won in the league earlier in the season but lost in the Capital One Cup after extra-time.
"The replay is not a problem for us," insisted the manager. "We’ve got plenty of time for it as we have no European games. I don't know when it's going to be played mind you, probably May because we've got the international break coming up! But the only thing we can say is we're still in the cup."
