Benfica is 3 points behind Sporting but they have 1 postponed match against team that is in the lower ranking, I think this postponed match will provide guarantee for Benfica to get 3 full points and match Sporting.
This weekend Benfica will play against Rio Ave away and Rio Ave itself is not team that can be underestimated because during playing at home it also showed that Rio Ave can perform optimally with fairly good game, however Benfica must still win this match because that way they will be able to continue to be below Sporting with difference of 3 points until they undergo the postponed match.
