A bit off topic but note Ange Pot, has selected 2 players from Portuguese top league in his recent Socceroos squads.
Awer Mabil (upcoming crucial qualifiers against Japan & Thailand) & Dylan McGowan (Confeds Cup) are both at FC Pacos de Ferreira (currently 15th in the League). Boyd's Tondela are 9th.
Like Boyd, Mabil's appearances to date this season have been a mix of starting and off the bench.
Sure far from an exact science, but if players from this league are good enough for Australia, figure Boyd is good enough for AWs. Have been a few doubting the standing of the Primeira Liga.
So really comes down to whether he wants to play for AWs, and if him & Hudson can bury the hatchet.
