I'm thinking like the main reason why David de Gea couldn't find a team for himself is his high salary expectation. He couldn't reach an agreement with Manchester United because of this reason. I thought that maybe Bayern Munich would be keen on signing him but they didn't want to go for him either. They preferred a young talent named Daniel Peretz instead.
If Bayern Munich didn't spend a lot of money on Kane transfer then maybe they would have made an official offer for de Gea who knows. Because it took them even a long time to reach an agreement for Kane transfer at a price as favourable as possible.
I personally not so sure de Gea is still demanding for a high salary, because if considered from the situation that happened like this then maybe in the transfer market later de Gea is willing to be paid lower . Anyway, basically de Gea age is also no longer able to play for the long term, so it is quite reasonable if big teams like Bayern Munich are not willing to pay expensive de Gea . Also, if de Gea demands to be paid dearly, then the only option is to play in the Saudi Pro League, but in fact de Gea also rejected the offer there.
Its a little strange that Bayern Munich would miss out on someone as good as de Gea. He had a great career at Manchester United, and he left an indelible mark there. Yes, he's old, but getting older can make you smarter, especially if you're a custodian. Thought it was admirable that he was ready to take a lower pay to stay in the EPL. What that says about how much he loves the game and the league is clear. But if the rumours that he's ready to quit if he cant find a big European club are true, its a sad sign of how cruel football can be. Although Bayern should jump at the chance, there may be more going on than we know. Also, imagine De Gea leaving the team without one last cheer! It would be a strange turn of events if that happened.
