The 23-year-old, who joined the west London club from Valencia in a five-year deal on Wednesday, used his twitter account to thank and praise Benayoun for consenting to the move.
Mata tweeted: "Very grateful for having been given the number 10..a pleasure and an honour for me, great player and better person, thanks Yossi!"
The development will increase speculation that Benayoun, who has made just seven appearances for Chelsea in an injury-hit spell since joining in July 2010, could be set to depart the club.
