Roma will take on Barcelona in the Joan Gamper Trophy.
The game will mark the return of Jose Mourinho to Camp Nou.
Mourinho was an assistant to Louis van Gaal for three years before leaving Barca in 2000 to become Benfica’s manager.
The former Chelsea coach became an unpopular figure at the Camp Nou after joining Barca’s bitter rivals Real Madrid in 2010.
Mourinho won a LaLiga title, a Copa del Rey and a Spanish Supercup in his three seasons at Madrid.
