Sporting Lisbon kick off the Portuguese league on Friday night. The champions host Rio Ave to introduce the domestic competition to the public. The Portuguese clubs will once again be aiming to unseat Ligue 1 as Europe's fifth biggest competition.
With the departure of Kylian Mbappe to Real Madrid and the problems of finding an attractive recipient for their television rights, the French are expected to go into a tailspin.
The first step of the Portuguese territory is the perfect suggestion to review the opening matchdays of each of these continental calendars and what their dates are.
