Barcelona coach Ernesto Valverde chose to clear the air with Vidal after the player had been chastised publicly by directors for his social media outbursts, according to Sport.
The coach spoke with Vidal 24 hours before their Champions League win over Inter Milan.
The pair thrashed out their differences, with Valverde making it clear to Vidal he needed to respect his selection choices and his teammates.
The Chilean agreed and was rewarded with an appearance as a second-half substitute.
