Making their investment into midfield and attacking line is crucial to bring back the same old domination for Bayern Munich. However I'm not sure about Declan Rice to choose them for now. Because it can be difficult to predict some English players' decisions after having their whole career in England until that time. For example it is valid for Harry Kane also.
Bayern Munich have already making a decision that they will withdraw to gets Declan Rice this because 100 million price tag by West Ham is too expensive for Bayern Munich and Bayern Munich have tried to negotiate but West Ham aren't willing to lowering the price and actually Bayern have money and it's not a big deal for them to pay according to Declan Rice price but their priority currently will looking for new strikers so Bayern Munich will not joining the race anymore to gets Declan Rice signs
Bayern Munich recently have already to gets Leipzig player Konrad Laimer and i think they will not pushing theirself again to gets new midfielder players anymore and it's time for them to looking for new strikers but so far there was no big names linked to them and about Harry Kane and Osimhen i think Bayern Munich will be so difficult to gets them because Tottenham or Napoli aren't willing to sell them
That's hell of a price tag for Declan Rice.

Maybe Bayern Munich are aiming to make multiple transfers in this transfer window so they don't want to spend that much on Rice already. His market value is 80 million and I thought West Ham would demand an amount around that level. Then this means Arsenal might also not pay that much for him if they don't aim to use up a significant amount in their budget quickly.
Price tags for Osimhen and Kane both must be around 120-130 million. The market is like this from now on so they had better get used to it. The cost of bringing a big talent is much bigger than the past.
I don't know who Bayern Munich would decide to go for but they had better sign an all-around forward like Lewandowski, Benzema and so on.
