As the Hornets prepare for their biggest game in many years, Gracia knows the pressure that his selection is under.
They face Manchester City in the final and will be hoping to pull off an upset.
"Yes, I have decided," he said of his starting XI to reporters.
"Always you can change something but when you prepare the game, I was thinking about it many days ago, and I think about how it is better to defend, better to attack and the players who are better to do that.
"At the end, you can change because I have different options, I want them all to play the final but that is not possible."
