Never said Dias price is cheap but definitely would be cheaper than those names i mentioned. Romagnoli would be great but my only concern is he want to stay in Italy and even if Milan want to sell him, he would cost around £90M - £100M or probably even more since he's Milan best player and their captain.
Zouma and Tomori are decent but i don't think both of them are good enough against Messi, Ronaldo, Aguero, and Mbappe. If we are truly aiming to win PL and CL next season, we needs to buy a WC CB since none of our current CBs are WC material.

I'm a big fan of Haaland, think he has higher ceiling than Tammy. The problem is most of our fans don't want the club to buy someone who will replace Tammy for ex: Werner and Haaland.
