Not exactly direct Algarvean interest, but lifted from World news .....

Belenenses named just nine outfield players in a match against Benfica on Saturday night, with the game called off at 7-0 when injuries reduced the team to six.

The Portuguese side could not field a full strength side due to a Covid-19 outbreak at the club, and rather than cancel the fixture and potentially suffer further penalties, the club went ahead without subs, and without the full complement of players.

Two goalkeepers were named to bulk out the team, and Benfica showed little mercy as they went ahead after just one minute through an own goal. 

6,06 fans probably won't get their money back either.

Scorn and shame for Portuguse football, an incomprehensble decision to refuse permission for a postponment, say overseas news media among other things.

Benfica themselves are quoted as saying, in effect, we should all be ashamed but it's not our fault. The normal process here is that a match abandoned is resumed from the point where it left off, i.e with Benfica 7-0 up. This could be an interesting test case.

By contrast and there is no mention of this on their website, Ferreiras' last two games in the Algarve League have been called off for precisely the same reasons as Belenenses were refused.
