Chambers is currently with England in Poland for the U21 Euros.
Reports have linked Everton and Newcastle with a £15 million move for Chambers, who was reluctant to discuss his plans for next season in any great depth after impressing in England's 0-0 draw with Sweden in Kielce.
However, Chambers was effusive about teammate Per Mertesacker.
“In the last few years he was my mentor," Chambers told Kicker. “I've never seen such a professional, dedicated player, I've learned from him every day.
“He kept me on track, reminded me of the little things that brought you where you want to go. He's a great guy.
“To learn from such a player and such a personality - I could not have done better. I just got better because I could train at his side every day."
