He said: "Judging by the stories in the newspapers, it looks as though a few clubs were interested in making offers for me.
"But I wasn't thinking of moving from Celtic because I feel I still have things to achieve at this club.
"I was really disappointed when we lost against AC Milan in the Champions League last season and I want to be there again.
"I wanted to be a Celtic player this season."
"I was just concentrating on being part of the squad and trying to play as many games as possible. That was the main aim.
"But two years later, I am still here and it's been a great experience.
"I have won four trophies, personal awards and I am playing for a world-famous club.
"It's been a good time in my career but hopefully there is more to come."
