I don't think it would be good for Lewandowski to go to another team. He may now consider retiring at Bayern Munich instead of adjusting to a new league. Because he's still playing very well and it can last another year or two. Lewandowski is the top goal scorer in Germany in recent years. If Bayern signs Haaland, then Haaland can overtake him. If he does not transfer, Lewandowski's records will not be broken for many years.
Haaland has the quality to break that record and if he will be playing for Bayern Munich maybe in the future its possible that he break it .
Dont know if Lewandowski will be retiring in Munich , as he wants to play and if Haaland will be coming i guess he will be leaving Munich.
The problem with Haaland is that he is often injured , but we will see what is coming , i also never expected Niklas Süle to go to Dortmund.
