Saturday's FA Cup final sees Crystal Palace take on Manchester United with the latter looking to win the cup for the first time since 2004.
"We have to be realistic. United should be fighting for every title. We didn't do that with the Champions League," said United midfielder Ander Herrera.
"We didn't do that with the Premier League. So we have two options. Firstly, feel sorry for ourselves. Or, secondly, get this trophy for the fans, for our club and for ourselves."
