The Spain international has netted four times in the league this season, but is still not regarded an automatic starter at Camp Nou.
"I know what the coach's starting XI is and I'm not in it. I played a good game at Celta [Vigo] and then I went almost two games without playing and that bothered me," he told reporters.
"I'm on good form, I always try to vindicate myself and make a difference, and I want to say that I hope it does not happen again."
Fabregas has also contributed seven league assists this season.
