Marc-Andre ter Stegen could reportedly leave Barcelona during this summer's transfer window.
The Germany international, who is Barca's undisputed number one goalkeeper, has made 223 appearances for the Spanish champions, including 33 in all competitions this season.
However, according to Cataluyna Radio, Ter Stegen is unclear whether he will be at the club next term.
The report claims that a Spanish journalist recently met with the German to discuss the possibility of collaborating on a book, but the stopper turned down the offer as his future at Camp Nou is up in the air.
Ter Stegen allegedly has a strained relationship with a number of first-team players at Barca and is believed to have had a training-ground row with Lionel Messi in the early stages of 2020.
The 27-year-old has a contract with Quique Setien's side until the end of the 2021-22 campaign, though, with his current deal believed to include a release clause of €180m (£156m).
