Juninho has admitted he is growing increasingly frustrated at not being a regular with Celtic.
“Every player is happy if they are playing and the feeling I have now is the way anyone not playing would feel,” the Brazilian told the Daily Record.
“All I can do is wait for my chance and try to prove my value and get back in the team.
“It is very frustrating for me but I have to learn this lesson.”
The 31-year-old joined Celtic from Middlesbrough in the summer but has been a peripheral figure since his arrival.
“I need Celtic and the people here to trust me again,” added Juninho.
“They have lost confidence in me. I need to recover that trust and the most important man to convince is the man who chooses who plays.
“I will just concentrate on getting the confidence but not mine – my belief is still there.”
