Turan is currently banned from playing due to a FIFA player restriction imposed on Barcelona prohibiting registering new players until January.
The bearded winger joined Barcelona on a five-year deal from Atletico Madrid over the summer transfer window but had to watch the El Clasico from the sidelines.
Turan shared a picture on Instagram alongside the caption: “Congratulations team.”
Luis Suarez opened the scoring with a wonderful finish using the outside of his foot within the first 10 minutes and Neymar doubled the away sides lead on 39 minutes.
Iniesta extended Barcelona’s lead further soon after the half time break and Suarez scored his brace on 74 minutes in what was arguably the attacking move of the game. Lionel Messi’s defence splitting pass found Neymar who provided an assist for the Uruguayan international.
