Manchester United manager Jose Mourinho admits his team will be stretched to their limits if they continue to progress in all their cup competitions.
The Red Devils take on St Etienne in the first leg of their Europa League last-32 tie on Thursday before the second leg follows an FA Cup clash at Blackburn. The frantic 11-day period then concludes with the English Football League Cup final against Southampton.
Mourinho is concerned that fighting on all fronts will create problems for his squad, but he insists they will try to win every game.
"We cannot choose the competitions at Manchester United," he told a news conference. "We know that our situation is really complicated. We know that the Europa League is also a competition where we play on Thursdays and that makes it even more difficult for us.
"The accumulation of FA Cup, League Cup, match postponements is really hard for us. If we progress in the competitions, we will be in trouble in April and May. But we cannot choose competitions, so we play them to win.
"I think it's also a good way to give the team experience and international experience is always a plus. Europa League is not a competition we want to play, but it's a competition we play and we respect it."
