A far bigger deal is made of release clauses than it should, they are mandatory according to Spanish & Portuguese law.
All it means is that they have to accept a bid of that amount, not that they won't accept less.
The absence of release clauses like with our players is effectively the same as having a release clause set at infinity.
The player is a bit raw and makes a few mistakes at times but has everything to be a top centre back. If we want somebody who will initially be an understudy and will eventually take over from Fonte, he fits the bill and is about as good as we can get.
Played a lot this year too, Sporting brought him back from his loan in January and immediately became first choice over Paulo Oliveira who has already been called up to the national team.
Besides, we no longer have a player who will get sent off three times in the same season.
