They have the best defensive record in the league, having shipped in just 10 goals.Portimonense have been inconsistent in their performances this term but have started to find the back of the net in their recent outings. While their 4-1 win last week was impressive, we don't think the club will pose any threat to Sporting's unbeaten run.We expect the runaway leaders to record yet another win in the fixture and the odds of a fifth clean sheet in six games look good.Prediction: Sporting 2-0 Portimonense.
