A very reasonable request, Nico Williams is worried that Barcelona will have difficulty registering him next season. Barcelona have certainly learned from their last mistake which was the difficulty of registering Dani Olmo, fortunately the situation did not interfere with their journey to win the trophy last season.
Juan Laporta said Barcelona are ready to pay Nico Williams release clause of 58 million, this statement can be interpreted as Barcelona having prepared everything carefully.
It is quite reasonable of Nico Williams to request that the registration process at Barcelona should be made fluent before he signs the contract. Such operations, as observed from the Dami Olmo case, Barcelona is not perfect in handling player transfers. Nico Williams would not want to find himself in a condition like that, where getting registered turns out to be a barrier to his career at a new club. The 58 million release clause will have been set by Barcelona itself; they must have gleaned their lessons and desire perfection in everything; Nico Williams’ plea results from the anticipation of not having anything untoward happening in the future.
