Real Madrid is trying to find a replacement for Dani Carvajal.
Recently one important thing for Real Madrid has been to have a good right-back player for a long time and that's why they are trying to find a young player for it.
Trent Alexander-Arnold is the player they want to hire and Real Madrid is ready to pay 80 million euros for him.
Real Madrid are the biggest club in the world, there is no doubt about that I think. As big as they are though, they will never get Trent Alexander Arnold to leave Liverpool. He is born and bred in the city, Liverpool is his team.
Besides £70,000,000 wouldn’t even buy his left leg

No way he goes to Real Madrid and I would take bets on that.
Well it is big money and it is still possible to happen especially now that Trent Arnold's contract will indeed expire in 2025 so anything is possible. But even so now business is talking. At the moment apart from Trent Alexander Arnold, it is also possible that they could still lose Salah because we know that previously the Arab club with big money has been rejected but for next season the offer is still there.
If in the end when the big money is obtained then it is possible for Liverpool to accept it and prepare to look for other alternatives as a replacement. But if still reluctant to let go then now Liverpool must try to fence Trent Alexander Arnold with a new contract because the end of the season ends then indirectly his contract and Liverpool are shrinking.
