Los Blancos are rumoured to be considering a summer bid for the 26-year-old right-back, but the Pole is refusing to discuss the issue until the Spaniards make a concrete offerBorussia Dortmund defender Lukasz Piszczek is remaining coy on speculation linking him with Real Madrid, insisting that his sole focus at the moment is Saturday's DFB Pokal final against Bayern Munich.
The Poland international's agent hinted on Thursday that his client would be open to joining Los Blancos, describing the newly-crowned Liga champions as a "worldwide legend".
Piszczek, for his part, is giving little away, arguing that there is no point in even discussing a move to the Santiago Bernabeu until Madrid make a formal approach.
"I'll only think about it once I have received a concrete offer," the 26-year-old right-back told Przeglad Sportowy.
"I am a player who only identifies himself with the club he is under contract to, so I'm only thinking of Borussia, who on Saturday are hoping to win the Cup final.
"And I am in tune with the club. Last summer, shortly after my contract extension, I bought a house near Dortmund."
Piszczek, who has been capped 21 times by his country, joined Dortmund from Hertha Berlin in 2010.
