Athletic Bilbao defender Aymeric Laporte is reportedly keen on joining Barcelona this summer.
The Frenchman, 19, is widely regarded as one of the best young centre-backs in European football, with his performances over the last 12 months drawing a host of interest.
Laporte hinted last week that he wants to remain with Bilbao next season, but according to Sport, the defender's head could be turned by a wage hike with the Catalan outfit.
It is understood that Laporte's buy-out clause is in the region of £29m, which Bilbao would demand in order to sanction a sale.
Bayern Munich are also believed to be monitoring proceedings.
