"We missed continuity this season in the Premier League," Mata told La Gazzetta dello Sport.
"Next year will be so different, and for me the Premier League is a challenge now. It is a trophy that I am missing and a trophy that I want to win."
Mata also insisted that struggling striker Torres still has a lot to give to Chelsea.
"I believe that Fernando still has much to give to Chelsea," added Mata.
"The way he trains and his mentality means that he still has many years at the top level left."
