Haaland told BBC Sport: "This season has been tough. It is not nice to lose so many games. It is boring and not fun. That's why we need to finish well and get a trophy.
"It is a good habit to reach Wembley and always important to win trophies. We have the FA Cup final to play for and in a horrific season we still managed to do this.
"When you have won four league titles in a row, if you don't win five it's not going to be a successful season.
"Those are the standards we have set. We haven't done good enough in the league but still hoping for Champions League qualification."
