With Lewandowski three seasons hot form and compared to the recent award of his, he is the man of the moment. Again for him not to extend his contract by now is a signal that might likely exit the club.
Lewandowski is unfortunately to be in a same era of Messi and Ronaldo then all of his magnifcient works have been unrecognized or under-valued because people are obsessed to think Lewandowski is at lower quality and level than Messi and Ronaldo.
With Lewandowski, if he had appeared and played in era 30 years ago, I am sure that he would have been one of biggest or biggest super stars. I know, back in the past, there are more stars than now and the competitiveness is much higher than now. It is abnormal to see 2 super stars dominated all personal tittle competitions for more than 10 years.
Honestly, if I were Lewandowski, I would have stopped and remained in Bayern. Be very loyal and become a renowned legend of the club.
In the world of football now, no where is sage.
It is better you remain where you are a king and where you are worshipped.
If he is to exit, anything that is not Real Madrid might not be considered fit to harbour Lewandowski(personal opinion)
Lewandowski makes his name in Dortmund and becomes a legend in Bayern. He does not need to contribute more for them, or play there and end his career there to be a real legend. He has already been a legend.
With strategy of Bayern and ambition of Lewandowski, it is very likely to see he leaves Bayern.
