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.
Liverpool used to appreciate their players because they try their best to keep most of these big names that are trying to leave at the end of this season, and most of these players rejected the contract offers because they feels like they are done with the club and they needed further challenge. The worst thing here is that, most of these players will be leaving for free, it will cost the team a lot of money to bring in new set of players to match their quality, and the team will struggle for like one season because the new players will need some time to adapt. Furthermore; if the team managed to win the Premier League title this season, they will earn some money they can use to sign some players if not they will have to face the financial fair play, and this will restrict them from getting quality players because players are very expensive.
