Apparently Arabian clubs hasn't stopped to hijack Liverpool players because after gets Fabinho and Jordan Henderson now there was other club who interested to Liverpool player Luis Diaz and it say Al Hilal who really serious want him and they will attempts to get him this summer and reported first proporsal is being formed that Al Hilal will bid not less than 50 millions and Liverpool hasn't respond it yet this rumour but most likely they will reject this offer because Liverpool still needed Diaz service especially after losing Fabinho and Henderson that they don't want to losing more players besides that Diaz too is important player for Liverpool and if he hasn't get injured Klopp was always playing him regularly
IMO, Liverpool do need an overhaul in their squad, they need fresher players. So, if there are several Liverpool players offered by the Saudi club. they can let him go, other than that Klopp will get additional budget funds to bring in the new arrival he wants. for Jordan Henderson, it deserves to be released and replaced by a younger player.
Fabinho, this player is also very inconsistent. however, it looks like Klopp could still keep him if he is included in his project next season.
To be honest, I don't know much information regarding rumors of Liverpool players.
for Luis Diaz, too bad he had to join a Saudi club. The problem is, he is still relatively young at 26 years old. Klopp can still very much count on him in his squad, so it would be a shame if he finally accepted an offer from a Saudi club. although Liverpool need new additional ammunition, I don't hear many rumors that Klopp is hunting for front line players. So, as you said Liverpool will not let Diaz go.
