Portugal stars Fernandes and Felix were in action against Switzerland in their Nations League showdown.
Former Manchester United star Cristiano Ronaldo put Portugal ahead with a stunning free-kick in the first half.
However, United fans were more focused on transfer targets Fernandes and Felix.
Sporting Lisbon midfielder Fernandes and Benfica forward Felix have both been tipped to join the Red Devils this summer.
Reports this week claimed United have tabled a bid for Felix, while the Red Devils are also battling with Manchester City for Fernandes.
And United fans took to social media during the Nations League clash, urging club transfer chiefs to sign the Portugal pair.
One fan wrote on Twitter: “Watching Bruno Fernandes & Joao Felix for the first time, both looking good.
“Felix is rapid and hungry – would love him at United.”
Another added: “@ManUtd joao felix please.”
“Bring joao felix and bump Fernandes to United already,” said a fellow United fan.
Another simply put: “Bruno Fernandes, our first big signing of the summer?”
“Ronny better be telling Felix and Fernandes to come United ya know,” said a fellow supporter.
Ole Gunnar Solskjaer confirmed before the end of the season that United have already held talks about summer transfers.
“Of course, we’ve been discussing how to move the club forward,” Solskjaer said.
“That doesn’t mean we’ve said x amount of money or x amount of players.
“We’ve sat down and discussed, but now it’s easier to be clear about what we need to do because we will do some business this summer.”
