With the Polish striker ready to leave Die Roten, the German club is looking for a suitable alternative if they decide to let the footballer go.

The current transfer window will keep fans refreshing their web browsers and social media accounts to see if their teams have added any more players, and judging by the kind of rumors that have already emerged, it seems like it will be one for the ages.

One of the most common transfer gossip this season is that about Robert Lewandowski, who is determined to leave Bayern no matter what. The player has been linked to Barcelona for the better part of May, but Bayern execs have been adamant about his future: Lewandowski will stay put at Allianz Arena. Nevertheless, a source close to the team has revealed that they would be willing to part ways with the Polish ace if they can find a replacement, and the same report has even named the player who could fill that void.

The player in question is none other than Romelu Lukaku, who has fallen down the pecking order at Chelsea and is looking for a way out of the Blues' discipline. The report by TuttoMercatoWeb states that the Bavarian side has already contacted the player's inner circle to offer him a three-year deal to become Bayern's new reference up front. If Lukaku agrees to join Bayern, then the German side would be willing to let Lewandowski leave.

Bayern's prospects to land Lukaku's signing would be good, especially since the other team interested in the Belgian ace's services (Inter Milan) have already voiced their interest to sign Lukaku on loan, something Chelsea would not be willing to accept. Hence, if Bayern come up with the money for Lukaku's permanent transfer, they would let Lewandowski leave while hiring a reliable replacement who is seeking for pastures new.

To make matters even more interesting, Chelsea have also shown interest in signing Lewandowski, which could result in a player exchange between the two European giants. 

Only time will tell where Lewandowski -and Lukaku- will end up playing, but the possibility of exchanging No.9 jerseys at Chelsea and Bayern seems feasible at this point.
