Mourinho's Benfica still unbeaten

Remarkably, however, that achievement will not be enough to deliver the club's 39th league title.

Porto have already been crowned champions after moving nine points clear of second-placed Benfica at the weekend.

Under the presidency of former Chelsea and Tottenham manager Andre Villas-Boas, Porto have lost just one of their 32 games this term.

While Benfica have not lost any, they have had 10 draws - six more than the champions.

Benfica will complete an invincible season if they avoid defeat against Braga on Sunday and Estoril Praia on the Primeira Liga's final day.

And this would even not be the first time they have gone a league season unbeaten and ended up trophyless.

In 1977-78, Porto drew two games fewer and pipped them to the league title on goal difference.

Mourinho's Benfica could join FC Sheriff in Moldova (2024-25) and Serbian side Red Star Belgrade (2007-08) as the only European sides this century to miss out on a league title despite going an entire season without losing.
