Juan Mata is grateful to Tottenham boss Andre Villas-Boas for signing him for Chelsea.
Villas-Boas was the man responsible for luring Mata to Stamford Bridge at the beginning of last season, and the Blues playmaker has nothing but kind words for the man who helped him settle in England.
"He was very important to me when I first arrived here and he gave me a lot of confidence so, of course, I'm very grateful," Mata told chelseafc.com.
"I haven't seen him since he left the club but I wish him the best of luck, although not during today's game."
