Mexico international Javier Hernandez has told Fox Sports about his frustration at Real Madrid.
Hernandez, 26, is on a season-long loan at Real from Manchester United but has struggled for regular first-team football.
The striker has made 13 La Liga appearances and scored three goals for Carlo Ancelotti's side but just one of those has been as a starter.
Hernandez, who scored in Mexico's 1-0 win over Ecuador on Sunday, said: "My situation is frustrating. I participate, give my all in training, but 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.
"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 need to be people who believe in me, at least so I can prove if I am any good or not."
