Roma youngster Salih Uçan has struggled for playing time this season but did manage to get some playing time against Barcelona in the 6-1 Champions League defeat yesterday at the Camp Nou.
Uçan replaced Pjanic on 75 minutes but his main contribution to the game was giving away a penalty on 77 minutes after bringing down Barcelona star Neymar.
The Turkish international midfielder spent last season on loan at the Italian giants but struggled for playing time due to injury problems. Uçan suffered four injury blows over the past season.
Roma agreed to a two-year loan option last season with a buyout clause option that they can activate this season.
Turkish referee Cüneyt Çakır who officiated the game awarded the penalty against his compatriot.
Roma remained in second place on five points following the defeat and could book a place in the Champions League Last 16 with a win against BATE on Match Day 6 if Bayer Leverkusen drop points against Barcelona.
