Signing a player like him for free will be a great job!
Real Madrid are now making it a habit, lol, they signed Kylian Mbappe for free and now they get Trent Arnold for free too, two of the best players in the world in their respective positions. Liverpool fans will be absolutely gutted, they will feel hard done that they are losing one of the best right backs in the world for free, when they could have easily got >60m for the English international, i guess Real Madrid are the winners in this deal.
Real Madrid have finally realized that as long as players are dreaming, they can confuse players for free. Every player whose contract is about to expire is on their radar. If the Trent Alexander Arnold transfer happens like this, every team will start moving early to increase their players' contracts.
