When asked recently about his future, Xhaka neither confirmed nor denied his intentions, leaving the door open to a summer move after seeing key players like Florian Wirtz and Jeremie Frimpong depart.
"Of course, the players who are leaving or have left are a huge loss, definitely," he said.
"They were extremely important for the team. With [Leverkusen directors] Simon Rolfes and Fernando Carro, we have enough players who can hopefully get the team back to that level. Whether it’s with or without me is another question. But as of today, I’m here. We’re happy, and that’s what matters.
"Of course, you think about it, but as I said, my mind is far away. I have my family and my management to take care of such things. When the time comes and you have an offer on the table, then you start thinking about it. And when the time comes for a transfer to take place, I’ll definitely let you know."
