Southgate delivered: “If the squads are going to be larger then it wishes to be a scenario where everyone is capable of exchange on a matchday.”
The closing date for all 32 countries competing to post their final squads is 20 October – 30 days earlier than the first recreation between Senegal and the Netherlands on the Al Thumama Stadium.
FIFA also stated that no more than 26 humans – up to 15 substitutes and 11 crew officials, of which one has to be the group physician – could be allowed to take a seat on the bench.
