"We want him to continue, but he also needs to make a decision about what he wants to do in his career. It is an uncomfortable situation.
"I wouldn't say that the extension is at an impasse, but he also has a personal situation with his agents that he has to resolve."
The right-back has previously been linked with clubs such as Bayern Munich, Atletico Madrid, Barcelona and Bayer Leverkusen.
