RIO DE JANEIRO - Botafogo sacked head coach Alberto Valentim on Sunday after the team's 3-0 defeat to Rio de Janeiro rivals Fluminense in the Carioca championship.

The result left Botafogo third in Group A and without hope of advancing to the competition's knockout phase.

The 44-year-old, who also managed the club in 2018, led Botafogo to just seven wins in 17 matches in his second spell in charge

Assistant coach Fernando Miranda also left his position, the statement added.
