The Red Devils are still chasing players for Jose Mourinho, who has expressed his frustrations with the transfer window so far.
Yerry Mina (center)What's the rumor?
Mina's agent, his uncle Jair, has previously confirmed that Everton have also shown an interest in his nephew.
Despite Everton's firm stance that a deal taking Ademola Lookman away from Goodison Park this season will not happen, Bundesliga outfit RB Leipzig continue to eye the player who impressed on loan in the Bundesliga last term.
"I hope I'm wrong - but I think it's going to be a long season for long suffering Evertonians".
It looks like Mina is determined to leave Nou Camp, and Everton and Manchester United would be the best suitors for him.
"We all want him to be at Lyon too, to play the Champions League at the GS", Aulas added.
To sign Mina, they will face competition from Everton, as well as a host of other clubs.
"If in every position you have very good players it's hard for the coach". If Manchester United can sell Rojo, it frees up a spot for them to then sign the Colombian. He had an impressive showing at the World Cup with Colombia, scoring two goals.
After his €11.8m move to Barcelona from Palmeiras in January, Mina had to sit on Barcelona's bench due to the presence of Pique and Umiti in the starting XI.
With the arrival of Arturo Vidal, Vidal takes up a non-EU roster spot that would have gone to Mina.
Silva seems determined to bolster his defensive options before they kick-off the new Premier League campaign against newly-promoted Wolves on Saturday and there could also be some departures from the club's attacking ranks.
