The Bundesliga giants have been constantly linked with a move for the Spain international over the summer, but the Basque side's president Josu Urrutia has remained firm in his belief that the 23-year-old will only move for 40 million euros.
That fee, which meets Martinez's release clause, has proved too much for the Bavarians, but, according to German newspaper Bild, the player's parents have now implored Bilbao to let their child departed for Germany.
President Urrutia, however, has remained steadfast in holding out for 40m euros, telling Basque TV station ETB: “We rely on our players from an early age, we want them to try and end their careers here.
“We do not do business with our players. It is a part of our history. In order for a player to leave Bilbao, he has to resolve his contractual arrangements.”
Bayern president Uli Hoeness has stayed firm on the other hand, saying: “A normal market value of Martinez is only 20-25 million euros."
