The former Borussia Dortmund ace had featured just three times for the Catalan giants prior to pulling up on his first league start in September.
Dembele was back involved in last week's Copa del Rey draw against Celta Vigo, however, coming off the bench for the final 20 minutes, before then playing three-quarters of the 3-0 win over Levante at Camp Nou on Sunday.
Speaking to reporters after the latest of those outings, the Frenchman remained upbeat that his best is still to come in a Barcelona shirt.
"I played on Tuesday against Celta, which was a difficult game, and now I had to play at home for the first time after the injury and I was excited," he said.
"I have a lot of work to do to get up to speed, but I'm calm. It was harder to maintain concentration and be consistent in order to meet the recovery deadlines.
"I know it is complicated and difficult to play in this team, but I like the philosophy of the club, which I have to learn. I have been learning about the dynamic of the group in the time that I was away."
Dembele boasted a 100% pass rate in the comfortable win over Levante, which maintained Barcelona's nine-point lead at the summit.
