"Does this mean all the players who are in the named 23-man squad must be in place in Qatar then? Or is it conceivable that other players could join up at a later date? If they arrive three days before, must they remain in Qatar and the team base throughout?" The football governing body replied and did not rule any of these options out. A FIFA spokesperson said: "In principle the participating teams should arrive in accordance with the FIFA Club World Cup Qatar 2019 regulations. Please understand we cannot speculate on potential scenarios."
