Jean-Joel Perrier-Doumbe is delighted to have re-signed with Celtic.
"It took about two months to sort out overall and I was never completely sure that I would be coming back here," he said. "But, right throughout the summer, I always wanted to come back. Celtic were always on my mind and this is where I want to play football.
"There were offers from France and interest from clubs in England but I wanted to finish what I started here last season. There is every possibility of more success and we'll see what happens as time goes on."
