Javier Hernandez has described his situation at Real Madrid as "frustrating" after managing only 590 minutes for the club.
The Mexico forward, who scored the only goal of the game in the national side’s recent 1-0 win over Ecuador, has been a peripheral figure since joining Madrid on loan from Manchester United last summer.
And the 26-year-old admits his lack of first-team action has affected his confidence.
He told Fox Sports: "My situation is frustrating. I participate, give my all in training, but as far as for playing in matches, the opportunities are minimal. I belong to a team, but am not part of the important bit, the actual games.
"Sometimes my confidence is right down on the ground, even though I am trying for it to be up there, with the help of the people who are always at my side and who support me."

Hernandez managed only six league starts at his parent club United last season and says his difficult term at Old Trafford was frustrating too.
He added: “The most important thing is to get chances, and to feel that they believe in you. Whenever they have entrusted me to do something it comes out positively, but I've been through two rather frustrating years.
"There needs to be people who believe in me, at least so I can prove if I am any good or not."
