​Former Barcelona star nearly joined Real Madrid in 2014 but faced bizarre contract hurdle – reportReal Madrid have been home to some of the best attackers in football history, including the likes of Cristiano Ronaldo and Ronaldo Nazario.However, one player they missed out on was Robert Lewandowski, who came close to joining Los Blancos in 2014.Lewandowski eventually joined Bayern Munich and went on to become one of the best number nines of his generation before moving to Barcelona.According to Diario AS, Real Madrid offered the Polish international a six-year contract with a gross annual salary of around €8.6 million, alongside a signing bonus of €10.95 million.Real Madrid’s unusual demands for LewandowskiLos Blancos‘ interest in Lewandowski intensified after he famously scored four goals for Dortmund against them in the 2013 Champions League semi-finals.Florentino Perez was determined to bring the prolific striker to the Santiago Bernabeu. The club were even willing to make a significant financial commitment to sign him.Robert Lewandowski went on to define a legacy at Bayern Munich.
