Barca sports chief Robert Fernandez is having Tah scouted this season - making a personal check himself.
The 21 year-old told BILD: "Barça's interest? It is of course pleasant to hear and it is an honor for me.
"After that, I do not know if it's true. From my point of view, Barcelona is an exceptional club.
"I think any young footballer would lie if he said that Barça was not attractive."
