Ibrahim had a three year contract with the Dutch club but left Eindhoven in December less than a year into that deal.
Neil Lennon handed the Nigerian a three and a half year contract last week with the player anxious to make an impact at Celtic after finding his development halted by the Swedish captain of PSV.
Ibrahim told The Sun: “It was unfortunate that at PSV my direct competition was the captain, Toivonen. He’s a great player, an experienced international.
“However, I do believe with good guidance I’ll get my chance here to prove myself at Celtic.
“I believe I will do that. I had a three-year contract at PSV, yes, but I had to leave because I was not getting playing time. We reached an agreement that I’d be allowed to go somewhere to get regular football.
“When I joined PSV, they liked me a lot but it was difficult for the coach to pick me ahead of the captain, playing in my position.”
