Derk Boerrigter admits he is growing frustrated at his current situation at Celtic.
The 27-year old Dutch winger joined the Hoops from Ajax in the summer but has managed just seven starts from his 22 appearances for the Glasgow giants this season.
Boerrigter admits it has been difficult to adjust to Scottish football under Neil Lennon but suggests he is not too far away from being a regular contributor for the champions-elect.
"Celtic's current tactics don't work to my advantage," Boerrigter told the Daily Record.
"The manager has asked me if I can eventually play on the left side of midfield in a Gareth Bale-type role and I like the sound of that. In recent weeks the team has been winning virtually every time and I have been a regular substitute.
"But it is my intention to get into the starting line-up in the foreseeable future. If that doesn't happen I will have to go and knock on the manager's door and we will need to talk.
"I have not come over here to sit on the bench. When I made my debut everyone, including the manager, raved about me. Sadly I've not got to play many games. I don't agree with those who say I am not cut out for the physical football they play over here.
"I spent three years in the Dutch second division and that demands other skills beside technical and tactical ability.
"I can draw confidence from having played in the Champions League. No manager would pick a player to face AC Milan or Barcelona if he didn't believe in him.
"It has been bitter for me to have my season overshadowed by my ankle injury. But once I am fully fit and back to my old level I know for sure that I can play an important role for Celtic."
