Van Buyten told the Scottish Sun: "Celtic is one of my options. I have not spoken with them but I know their coach has asked for details about me. Scotland is a fabulous country for football and the atmosphere is great.
"I arrived at Bayern with great hopes. My objective was to win a fight to win a place in the team and play in every match. Unfortunately, this has not been possible and I am unhappy about the situation.
"I'm working very hard every day but the coach doesn't seem to have confidence in me. After I speak with Bayern I will know my future but I will discount nothing.
"There's also interested clubs in England but the final decision is down to Bayern."
