The Catalans' trainer was impressed with the versatile midfielder's performance, and also had words of encouragement for Pedro
The former Arsenal midfielder featured from the start in Barca's 1-0 win over Los Che, and Vilanova was impressed with Song's performance.
"Song did a great job. He’s only had a few days of training with us. He picks things up quickly. He’s an intelligent player," Vilanova stated at a press conference.
"He’s talented on the ball, and he associates well with his team-mates on the pitch. He passed his first test at Camp Nou with flying colours."
The Barca coach then went on to discuss Pedro's start to the 2012-13 campaign, and had positive words for the fleet-footed attacker too.
"He’s had a great start to the season. He’s a player who always has chances to score, beyond everything that he brings to the team. He works a lot of defence and he wins back a lot of balls."
Barcelona sit first in La Liga at the moment with nine points from three games.
