Arsenal want to sell defender Calum Chambers and will open negotiations with Newcastle United and Everton in the coming days.
The player is expected to meet with his club in July after the 2017 UEFA European Under-21 Championship.
He will be told that that it will be very difficult to enjoy regular first-team football at the Emirates.
Asked about his future, the youngster opted for a "no comment" but was full of praise for Arsenal teammate Per Mertesacker.
"In the last few years he was my mentor," he 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."
