Not sure if you're talking about Alaba, but if so - David Alaba's £12m-a-season wage demands 'could derail summer move to Real Madrid' | Daily Mail Online
The wage alone offered by both clubs was significantly different & that's without mentioning the sign on fees to multiple people, which you touched upon. They will do the same thing with Rudi & Mbappe (doubt anyone will even make a move).
The passage of play prior to winning our second PK was something that enabled him/Inter to do so well last season. Someone mentioned it previously, but our reluctancy to move the ball quickly in attack hampers his play/output drastically.
From what I've heard, it seems very similar to the Alaba situation; Bayern offered him quite a bit to renew, but RM blew it out of the water. If this happens to be the case, we ought to move on as @Pizy alluded to.
Not sure how you know what the Vax rate is for players that will be participating at the tournament.
It still taking place in Africa is the one worry of note IMO.
