Considering social media posting
The user might want to share this as a social text, so I'll think about offering some refinements. My approach will be minimal and concise. I’ll provide an English translation along with an optional polished version. I’ll also check if they want context about the people and rumors involved.

So for example: "Caro says Wirtz would follow if Xabi Alonso came calling, but Alonso doesn’t carry much influence at Real Madrid.”
English: “Caro: If Xabi Alonso made an offer, Wirtz would go—but Alonso doesn’t have that much pull at Real Madrid.”
Polished: “Caro says Wirtz would follow if Xabi Alonso came calling, but Alonso’s sway at Real Madrid isn’t that strong.”
Want context on who “Caro” refers to or the transfer rumor?
