Manchester United had an official at Saturday evening’s match between FC Porto and Vitória de Guimarães.

The Red Devils have a long history of scouting Portuguese matches, but since Covid-19 hit, lists from clubs in the country of who is attending games have been much rarer.

When Manchester United scout games in Portugal it’s usually home matches of the big clubs, and whilst that’s the case with Porto it’s a little more unusual that this match was away.

It wasn’t only Erik ten Hag’s side who had someone in attendance, report O Jogo. The Manchester United official was joined by others from Borussia Dortmund, Real Sociedad, Rennes and Bologna.

Indeed, O Jogo say that group of clubs was just part of a more extensive list.

The Porto player Manchester United have been linked the most with is goalkeeper Diogo Costa. With uncertainty around David De Gea’s future and transfer situation, Costa has repeatedly been pushed forward as an option.

He’s had some great performances in the Champions League, but failed to shine under the bright lights of the World Cup, which would bring some doubt to the table.

As for his performance in front of the Manchester United transfer spy, O Jogo say he didn’t have much to do.
