I don’t know what is going on with Liverpool, they seem not to appreciate their players. Van Dijk would have been a very smart addition to Real Madrid if not for his age. When you consider his age there is reason for Real Madrid not to consider signing him. Real Madrid have a policy with aged players, I doubt if this transfer will happen but we will see how things unfold in the summer window.
The problem is that nowadays older player don't understand that they can't keep asking for a ton of money when they are at the end of their carrier. It could be because they know there is someone willing to pay them what they ask but they also must understand that they are playing a dangerous game because do you guys remember what happened with De Gea? He was asking a ton of money and at the end he didn't play for a year and ended up signing with Fiorentina, earning way more than what United was offering him.
