The attacker's representative has revealed that the Santiago Bernabeu side were keen to lure him to La LigaRobert Lewandowski's agent Maik Barthel has claimed that Real Madrid attempted to hijack Bayern Munich's move for the Borussia Dortmund striker.
The Poland international signed a five-year deal with the Bundesliga champions on Saturday to bring a protracted transfer saga to an end.
However, Barthel has revealed that Madrid were keen to sign Lewandowski, too, and were willing to go far for the 25-year-old.
"There was an immoral offer from Real Madrid," the striker's representative was quoted as saying by Spiegel Online.
Madrid were reportedly willing to offer Lewandowski an annual salary of €9.5 million plus an additional €10m signing fee, but Barthel has made it clear that they never considered breaking their promise to Bayern.
He added: "We listened to their offer out of respect for such a big club. But breaking our word never crossed our mind."
Lewandowski has been in sublime form for Dortmund this season, scoring 11 goals in 17 Bundesliga appearances.
