Signed for Dublin city rivals Bohemians in 2010 and made his debut in an FAI Cup semi-final defeat to Sligo.
Roberto, whose father hails from Cape Verde, played both at centre-half and in midfield at Bohs and was their 2015 Player of the Year. Roberto had been club vice-captain and their longest serving player along with Keith Buckley before Rovers captured his signature last year. In 2016 he got the winning goal in the derby between the Gypsies and the Hoops at Dalymount Park. He also helped Bohs to their only trophy success in the last seven seasons by scoring twice in the Leinster Senior Cup final against Wexford Youths.
He has scored once in 36 appearances for the Hoops, a header in the 1-1 draw at home to Limerick in April.
