The fullback arrives from Lille, with his move confirmed today.
Pinto said, "We are really happy that Celik has decided to come to Roma: his determination in choosing to marry our project is an indispensable prerequisite for creating an increasingly motivated group of players.
"In addition, despite being still young, Zeki has already accumulated a great deal of international experience, which will prove to be very useful in the the team's growth path."
Celik has signed with Roma to 2026 and added: "For me it is an honour to play for such an important club: I have great ambitions and I want to contribute to the success of the team. I feel ready and focused, I never give up and you will always see me fighting on the pitch."
