LISBON, May 1 (Reuters) - Sporting and arch-rivals Benfica remained within two points of each other after both posted victories on Sunday in the race for second place in the Portuguese first division and a Champions League third qualifying round spot.
Porto, crowned champions last week, celebrated the title in style at home with a 3-1 victory over relegation-threatened Vitoria Guimaraes, with Argentina midfielder Lucho Gonzalez scoring twice and Brazilian Adriano also on target.
With one game left, Porto have an unassailable nine-point lead over Sporting, who need one point when hosting Braga next Sunday to clinch the Champions League spot.
Sporting with 69 points, beat Rio Ave 3-1 away with winger Nani and Brazilian striker Liedson scoring in the first 20 minutes. Defender Milhazes pulled a goal back for Rio Ave six minutes later but an own goal by Danielson restored Sporting's two-goal lead.
Outgoing champions Benfica, without injured midfielder Simao Sabrosa, beat Vitoria Setubal 1-0 with a header by Brazilian defender Anderson after 22 minutes.
Porto could win a domestic double on May 14 when they play holder Vitoria Setubal in the Portuguese Cup final.
