Of course fans don't like hearing these rumors because Alexander Arnold is an important part of Jurgen Klopp's long-term project and his aggressiveness in helping attack and defense is of no doubt. Not only that, he is a complete player, he can be a RB or CMF if needed. Apart from that, he is also a specialist in free kicks, corner kicks and long passes. I think Real Madrid will be happy if they can get his services considering that there was no better executor when Toni Kroos left Real Madrid. A fee of 80 million is not too big for Real Madrid and maybe Real Madrid will provide add ons in the deal later to make this transfer from Liverpool easier.
Real Madrid needs new prominent players that will fill in the shoes of the old ones who have faded in performance, watching them in games doesn't spark any interest anymore because they're players with experience but doing the long runs to cater for the ball, seem to be struggle for them consisting their age and performance. Scouting for Liverpool backline, Trent Alexander-Arnold who is keyman under Jurgen Klopp in Anfield and losing him to Real Madrid is totally not the plan. Every clubs needs a potential player that's versatile and capable of reaching his peak, more reason they ought to be valuable in the market.
I see that what Real Madrid needs most this season is a striker who has good quality. Currently, Real Madrid's front line performance is very inconsistent, especially after they lost Benzema. Until now there is no player who is capable of filling the void.
For Real Madrid's midfield, it is very good, some of their potential young players have shown good regeneration. And for the bottom line, it is actually good too, but some of the older players need rotation so that regeneration is not slowed down.
