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.
