Fifa president Gianni Infantino has been urged to provide an additional minimum of $10 million (£7.5m) to all 211 member federations over the next three years from existing reserves.
The presidents of Uefa and Concacaf wrote to Infantino on Friday, noting their analysis indicated this sum represented a "conservative" figure of what the organisation could give each national body. They stated Fifa is set to end the year with reserves reaching $6 billion (£4.5bn).
