Mata knows how highly regarded Zola is by Blues fans.
"I know that, for the Chelsea fans, Zola is a legend," he said. "He won big games and titles for the club and was a fantastic player, who played with fun and entertained the fans.
"For me to even be compared slightly with him is a real compliment. As far as I'm concerned though, he did everything with Chelsea - and I only just got here."
