Savio, a club record buy in January from Italian side Brescia, is another who is gradually making his mark on the Premier League and Zola was pleased with his game-turning cameo.
"Savio has done well, the boy came on today and played a good game.
"I'm pleased for him because he came here with a lot of expectations and to be honest he was a little bit under pressure because he knows people are waiting for something special from him.
"But I'm pleased with how he is working and his attitude is good. He is going to be a successful player here I'm sure.
"We bought him because he has something different, something that is sometimes missing in a game and today we saw a little bit of that.
"I'm sure there's still a lot to come from him."
