I agree, the dippers are in a tricky position especially if Salah leaves too.
But it's amazing to me that every pundit just presumes that Alonso will automatically leave Leverkusen to go there.
Why?
I understand he's a top prospect, but so were others who haven't fared so well in similar circumstances, Potter and Nagelsmann as examples.
But also from a footballing point of view, he's got his team top of the league and if they win it, i can't see him going anywhere.
Even if they don't win it, they will likely qualify for the CL anyway, so maybe he wants to show some loyalty and see how he fares in that before he takes the next step professionally.
