But despite playing 12 times this term, Valverde’s sacking put Perez’s future in doubt and new coach Quique Setien has agreed to let the 21-year-old leave.

“We are hugely satisfied with Carles’ arrival in Rome,” said club chief executive Guido Fienga.

“Carles learned his trade in one of the best youth academies in Europe, and has been playing for a club with so much talent at its disposal. We are all hopeful that he can immediately have a significant role to play within our squad.”
