The Polish striker changed his agent in recent days to prompt suggestions that he was ready to leave the Bundesliga giants in the summer
Jupp Heynckes claims he "can't imagine" Bayern Munich sanctioning the sale of Robert Lewandowski after the striker's recent change of agent prompted fresh transfer links with Real Madrid.
Lewandowski is said to have severed ties with Cezary Kucharski, previously his agent for 10 years, in favour of Pini Zahavi, regarded as one of the football world's leading representatives.
Zahavi played a role in Neymar's world-record €222 million switch from Barcelona to Paris Saint-Germain in August and there have been suggestions Lewandowski's decision has been made with a view to securing a big move to Spain.
