The championship is about to begin. Relive the last 10 winners in Portugal.

To date, the I Liga has been won by only five different clubs, three of which stand out, with 20 or more titles.

For some reason, Benfica, FC Porto and Sporting are among the three so-called 'big' clubs, having been among them the 'division' of titles in the last ten editions.

The championship kicks off this weekend, and two-time champions Sporting are looking to cement their title, while their direct rivals are also betting heavily on lifting the trophy again at the end of the season. Who will be the next winner of the I Liga?
