Portuguese publication, O Jogo, are reporting that Arsenal and Manchester United had scouts at the game between FC Porto and Vitória de Guimarães at the weekend.
This is far from the first time that Arsenal have sent scouts to watch Porto and they certainly picked a good game to watch, with Porto winning 3-0 and a number of players performing as if they were aware there were scouts in the crowd.
So who where they there to watch? There are a number of possibilities, but O Jogo seem to think that it was Oliver Torres who is on loan from Atletico Madrid.

The 21-year-old attacking midfielder (you know he has to be an attacking midfielder because Arsenal are interested) can also play on the left or right wing and reportedly has a buy option in his loan deal with Porto this season.
A current market value of £11.9m, Torres scored in Porto’s 3-0 win on Saturday .
