More than 10,000 people took part in a poll to select a clairvoyant animal. Citta beat Mia the penguin and Denar the giraffe, who were also in the running.
Citta correctly picked Poland to win a pre-tournament friendly against Lithuania on Tuesday.
She will choose a winner or draw by selecting a piece of fruit.

Citta was also chosen to predict results in the 2012 EURO football tournament, hosted in Poland and Ukraine. She proved more decisive than the parrots and more focused than the donkey.
She had some success but did in one case choose to eat a football rather than use it to make her pick.
Citta is an Asian elephant who was born in wild some 40 years ago. She spent some time working in a circus. She shares an enclosure at the zoo in Kraków with 58-year-old Baby.
The World Cup kicks off on Thursday and runs until July 15.
