This game is on espn3.com Duarte has made just one 34 minute substitute appearance in the league to date.
Nacional lost 2-1 today (No Sergio sighting) but two of the regular starters got red cards meaning that Sergio has a good chance to make the bench next match.
He's been playing at SC Mirandela this season which is in Portugal's 3rd tier. He has 13 appearances thus far and seems to be a mainstay in the starting lineup. I'm unsure but I think this is also a loan.
Duarte has started 20 of Mirandela's 21 games and chipped in two goals lately. Portugal's third division has a split season format and Mirandela didn't qualify for the promotion group (only the top two in each of the eight regional divisions qualify). They are in a relegation group despite being a slightly-better-than-midtable club so it doesn't seem like they have much to play for. Being a regular starter is good, but it's hard to say if he'll be able to step up and play a role for Nacional next season. I guess we'll just have to wait and see.
Duarte has been sent on loan again this season. This time to Lusitano Futebol Clube, who play in the 4th division of Portugal (as far as I can tell). Here is the club's brief write-up about it. http://www.lusitanofutebolclube.pt/noticias.asp?idnot=1066 I have to say I'm a bit surprised he's going down another division after seemingly being a solid starter in the 3rd tier of Portugal.
It looks like Lusitano were promoted to the 3rd tier this season, so Duarte will be at the same level he was last year.
Sergio is still slogging through the Portuguese third division. Now at União de Leiria. http://us.soccerway.com/players/sergio-daniel--duarte/252500/
Sergio is now with FC Felgueiras 1932 who play in Portugal's Campeonato de Portugal (Serie A) he is playing regularly, and his team sits in 6th place - he is on my track list - so you can expect more on Sergio this season
Yesterday (Sunday) Sergio started, went 90 as FC Felgueiras 1932 had little trouble disposing of Cacadores Taipas 4 - 1 in Portugal's Campeonato de Portugal (Serie A)
