Many players imitate the way world stars like Cristiano Ronaldo celebrate when they score goals. But professionals in Poland are threatened with a penalty if they imitate striker Kechtow Piontik, who has unprecedentedly protected his celebration.

And moved the dangerous Polish striker from Milan, Italy to Hertha Berlin, Germany at the desire of coach Jurgen Klinsmann, and Berlin signed a contract with Biontech (24 years) for 22 million euros for the Italian club, and a contract that extends until 2025.

Biontech scored 30 goals last season in 42 games, and he singled out a distinctive style of celebrating goal scoring.

After scoring a goal, the Polish striker heads to the edge of the field, skating on his knees, and then folds his arms as if he was carrying a pistol in each hand, shooting bullets left and right.

The German website "Bild" mentioned that Biontec registered his method of celebration at the patent office in his country, Poland.

"The way the celebration was registered has many forms of protection for it as its own brand, and any professional in Poland who imitates this movement will have to pay a fine," said Edita Demba Seuk of the patent office.
