Barcelona midfielder Miralem Pjanic has voiced his frustrations over a lack of playing time under Ronald Koeman at Camp Nou.
The former Juventus man arrived in Catalonia as part of a swap deal involving Arthur last summer, but he has struggled to make a lasting impression with La Blaugrana so far.
Pjanic started all of Barcelona's group stage matches in the Champions League, but he has featured from the first whistle just five times in La Liga, although he has insisted that he will continue to fight for his place.
Speaking to Telefoot, the Bosnia international said: "The exact reasons why I've not had the playing time expected, I don't have them.
"I keep working and you have to respect the decisions that are taken, even if you don't agree. I want to leave my mark at this club."
Pjanic came off the bench for the final 18 minutes in Saturday's 5-1 victory over Alaves, and he is yet to register a goal or assist for Barcelona this season.
