"I think everybody is suffering," he admitted. "That is not a bad thing. It's really hard for the team, the staff, for everybody else but, especially, for our supporters, to lose that final. I think we did everything to have a different result but, in the end, we lost and now we have to forget that and focus on the last game at home, with our fans, and move on. That's important.
"Not just Sunday but in the future, especially in the future, we must use all this pain we have during this season in the last game but especially in preparation for next season."
The clash with Champions League-chasing Villa kicks off at 16:00 BST.
