The 1-0 win in northern Portugal sees the defending champions move one point clear of FC Porto, who had earlier beaten Tondela by four goals to nil.

Sporting are set in the third-place after beating Rio Ave in Lisbon.

Portimonense have meanwhile extended their lead at the top of the Second Division despite being held to a draw by Cova da Piedade.

This comes after the teams in second, third and fourth place all lost.
