Despite the team's impressive start to the season, Torres has been the target of some criticism for his performances but Mata believes that his fellow Spaniard's attitude in training is a sign of things to come.
"I believe that Fernando will score goals, because I know him, I know how hungry he is inside himself," Mata told the Daily Mirror. "Every day he is looking to score. Every day he trains so hard. I know how he is inside his own mind.
"For sure he is going to score goals. He is still young, only 28, he has some years still to go. I believe in him because he is a true person and very professional."
Torres is expected to start against his former side Liverpool at Stamford Bridge on Sunday afternoon.
