Luis Suarez was again on Barcelona's scoresheet in their Copa del Rey semifinal win at Villarreal.
Suarez and Neymar (2) struck in the 3-1 triumph.
"A berth in the final is special. After so many years to get to five in seven years demonstrates the greatness of this club," said Suarez.
"A final is 90 minutes and you never know what might happen. Players know when can't afford a yellow card and I knew how to deal with the situation.
"Obviously when you're Barça you have to try and win every competition you have. I know what a final means and we'll try to win it.
"Every week I try to help the team and every week I feel better on the field and that gives me more peace of mind."
