The 25-year-old is now targeting the successive matches against pool leaders Schalke as Chelsea seek to finish top of the group.
"We have two games in a row against Schalke and we will try to win all six points," Mata said.
"It's going to be difficult. They are top of the group right now, but if we do it we will be in a good position to qualify.
"We have qualification in our hands. We needed to make up for the last game and we did that. Now the story continues and we have to keep winning game after game and finish top."
