According to Spanish publication El Confidencial, Real Madrid have been informed of Chelsea’s offer and have been told to act quickly if they are interested in signing the Polish hitman.
Lewandowski is able to speak with foreign clubs from January 1 over a pre contract agreement for next summer, although Chelsea may speed up the deal by making a bid for the striker to give Dortmund an incentive to sell.
Bayern Munich are still the favourites to sign the 25 year old who has been in stunning form over the past two years for the impressive German side.
Dortmund are resigned to losing their main man but they are trying everything in their power to prevent him joining rivals Bayern Munich, who are already clear at the top of the Bundesliga.
Chelsea’s mega contract offer is a sign of intent with Mourinho not convinced with his current strikers Demba Ba, Fernando Torres and Samuel Eto’o even though the Blues boss allowed Romelu Lukaku to leave the club on loan.
