In the 2005-06 season Sport London e Benfica (SLB) changed from playing Sunday League to Saturday League football, joining the Middlesex County Football League, part of the National League System. In its first year of National League System football, the club finished top of Division 1 at the first attempt. The following season, in the Premier Division, José Viana's squad repeated their success by becoming Champions once again. This achievement means that Sport London e Benfica was promoted to the semi-professional leagues, the first Portuguese team to do so in the UK.
