For the few teams I no that isn't always easy for Porto, Guimaraes usually prove uneasy for them and unfortunately Porto has lost to them before so actually except that Guimaraes did not make changes on there striking strength before they cannot make it uneasy for Porto as they did the last time but however you are right about this top three because is likely going to present this way but if there is any club that would be unfortunate among them not to be on the top three the replacement that might come for it is Moreirense because they're also as strong as this three teams.
So far the championship has started without any unexpected results, Sporting and Braga easily beat their opponents, and I think Porto should also beat Guimaraes, although despite the home match Guimaraes can be considered a tough nut to crack. And as I understand it, since Benfica has qualifying matches with Nice, the start of the season will be postponed a little later for them. Guimaraes has a good attack, so I think they can score today.
Yeah we could have seen an unexpected matches if either Sporting or braga could have lost on the goals they gave there opposite teams, it has been a good starting for Sporting winning Casa pia AC 2:0 and also for Braga to also win Tondela 3:0 by scoring higher than Sporting, from the three clubs we believe are the best is remaining two to play there first match for us to see if they can as well get there three point as Sporting, Benfica will be remaining after Porto today and would match against CF Estrela da Amadora. However all this matches they both play non of them was under championship match.
