I don't think Florian Wirtz will stay at German. Until now, it is quite doubtful that Bayern Munich will sign him. The latest news reported that he will move to Liverpool. Wirtz stated he prefers Liverpool than any other teams. It means there will be no chance that Xabi will bring him to Real Madrid since he is only interested to join Liverpool.
Florian Wirtz total contract with Bayern Leverkusen is 7 years and from when he has been playing for the club 5 years has gone while he has more two to finish up. However I think all the players Liverpool had earlier intend to signed Florian Wirtz is the major one they want to get first because i think his role in the midfield is more than Dominik Szoboszlai but though I'm not comparing them but I'm eager to no why Liverpool wants him so much, however Florian Wirtz didn't just made a good choice in going to premiere league but also a good choice of club, i also love how bundesliga players do in premier League.
