It seems Newcastle United officials have spent a few days in the north of Portugal to keep an eye on local clubs in the past week.

Back on Thursday, club officials had watched Braga playing Brondby for the qualyfing rounds of the Europa League.

Now, as reported by newspaper A Bola, they’ve also seen Porto playing Vitória Guimarães for the Portuguese league.

It’s not made clear who the Magpies were watching this time, and since it’s early in the season, it’s hard to think of a target.

Porto striker Moussa Marega has been linked many times in the past year, but the chase never truly materialised, and he may still be off to AC Milan this summer.

But there was another Porto striker who impressed everyone at the Estádio do Dragão on Saturday night. Zé Luís scored a hat-trick, and now has four goals in four appearances this season. Luis Diaz also popped up on the scoresheet in the 4-0 win as well.

Atalanta, Manchester United, Strasbourg, Borussia Dortmund and Real Valladolid were the other clubs who had scouts at this game.
