Palace is reportedly willing to offer £45 million as its initial proposal to acquire Diomande. However, Sporting CP wants £50 million for the defender, which might lead to negotiations.
It is suggested that Palace is planning to bid aggressively for Diomande, knowing that they will be selling Marc Guehi to another club in the coming weeks. Several teams, including Newcastle and Chelsea, are interested in Guehi.
Diomande has also caught the attention of Arsenal, but Palace is planning to take action first in the coming weeks to secure the defender's services.
