Barcelona’s squad remains packed with talent including two-time Ballon d’Or winners Aitana Bonmati and Alexia Putellas.
The Spanish giants have won three of the past four Champions League titles and go into Saturday’s game as favourites.
“It is good that we have been given the favourites label but we know how important this is,” said Bonmati.
“Although it’s a new rival that has not been in the final for years, it is not an easy match. We still need to win the game and anybody can win.
“I said a few days ago it was a surprise that Arsenal beat Lyon [in the semi-finals] but they deserve to be in this final.
“They scored four goals against one of the best teams in Europe. We didn’t score four goals against Lyon.”
Putellas believes Barcelona’s previous success has given them experience and confidence but they still have to perform against Arsenal.
“Despite having three Champions League [trophies], it doesn’t mean we will win. It doesn’t matter how many finals we have been in,” added Putellas.
“It is true, we know what we have done, but it means nothing on your day-to-day work. You always want to go to the next level. The next goal is tomorrow’s final.”
The defending champions will come up against former Barcelona midfielder Mariona Caldentey for the first time.
She has had a brilliant debut season with Arsenal, winning the Women’s Super League Player of the Season award and contributing heavily to their European success.
“Mariona is an excellent player and knows her position extremely well. We miss her but we are happy she is having a good season,” said Bonmati.
“She is an excellent colleague – we wish her all the best but not tomorrow. Sorry about that!”
