The Mirror says Lewandowski has parted company with his agent Cezary Kucharski, and teamed up with Pini Zahavi.
Kucharski was spotted in the VIP box at the Santiago Bernabeu in December, telling Der Spiegel that he had opened talks with the Spanish giants.
"I am glad that Robert decided to co-operate with me," Zahavi told Przeglad Sportowy. "I will do everything to work well in his name.
"He is a great footballer. He is the best striker in the world. Therefore, it is not surprising that I have signals about the interest of his person in all major clubs."
Zahavi however was remaining coy over whether his arrangement with Lewandowski could see him leave the Allianz Arena.
"Will Robert go to Real Madrid?" he added. "We'll see. Now it's time for me to do my job."
