Clube Náutico Capibaribe
The rivalry between the two clubs is intense and is reflected in part by the opposing teams' colors: the principal colors of Clube Náutico Capibaribe are red and white; those of Sport Club do Recife are red and black. The competitiveness has sometimes given rise to conflicts between the supporters of the teams, especially among organized members of the teams' fan clubs. Security has been a significant concern for the local authorities, involving large numbers of police and firefighters.
