Javier Hernandez says his frustration at not starting for Manchester United will never affect his performances.
The Mexico striker's opportunities have been limited since Robin van Persie's arrival, and his eight Premier League goals this season have come from just six starts.
But Hernandez has told Sir Alex Ferguson he will be ready when called on as United aim to close out a 20th English title success.
"All the players in the world want to start every single game," he said.
"I am happy to be at this club. Of course I would love to start more often but I will keep the same attitude.
"When the gaffer wants me on the bench or the starting line-up I will do my best. My attitude is going to be very good because I want to respect the club, my team-mates and the coach."
