Arsenal boss Arsene Wenger says English clubs should be loyal to UEFA.
Wenger was asked about rumours of a breakaway world league this week.
He said: "It is a real danger because if tomorrow you have 10 South American or 10 Chinese who own 10 of the English clubs, they can say, 'Let's make a league and play some games on our continent' and all get together if they buy in different countries. It is a danger.
"That is why I believe and would fight that Uefa keeps control and that Fifa keeps control of the whole system."
