Warner has been a member of the Fifa executive committee since 1983. He first became secretary of the Trinidad and Tobago Football Federation in 1973 and president of the CFU in 1990. He has been described as tireless labourer in his pursuit to make Concacaf a better and stronger sporting organisation, and his vision has lifted Concacaf to heights never previously explored in the region. Under his leadership, new competitions have been created, while others were overhauled and improved. One of his goals remains wanting to see every member of Concacaf achieving sustained improvement in all facets of the game. Others nominated without opposition for positions on the Concacaf executive committee are Lisle Austin of Barbados (vice president - Caribbean Zone), Mexican Football Federation president Justino Compean (vice president - North Zone) and Ariel Alvarado of Panama (member - Central American Zone).
