The 25-year-old earned the transfer after an impressive loan spell with fellow Hungarian outfit Nyiregyhaza Spartacus during the second half of last season.
Tijani scored eight goals and provided three assists in just 15 league appearances, establishing himself as one of the standout performers in the division.
Ujpest sporting director Pal Dardai welcomed the signing, describing the forward as a major boost to the club’s attacking options.
“Tijani is a quality player who is a real reinforcement in the attacking line, where based on his abilities he solves problems that have been a serious problem until now,” Dardai told the club’s official website.
“His speed, physique and intensity of play will fundamentally contribute to our game becoming faster and more agile next season. I am happy that he has arrived and can immediately get involved in the work.”
