The towering 23-year-old centre-back, who impressed for Colombia in the World Cup, has struggled to settle at the Camp Nou since his arrival in January and failed to break into the first-team picture on a regular basis.
Everton had been linked with Mina but he is thought to prefer a move to United as the Red Devils prepare to conjure up a £35 million offer.
That sum is lower than Barcelona’s £50million asking price, nevertheless, the Spanish giants could be happy to get the former Palmeiras man off the books.
Mina would add significant robustness to Jose Mourinho’s defence at a time when their hopes of signing Leicester Harry Maguire begin to fade.
Barcelona face competition from Serie A giants Inter Milan in the race to sign young French midfielder Lucien Agoume.
According to France Football, the 16-year-old talent, who is part of Sochaux’s Under-19 side, is on the radar of the Blaugrana after impressing in the Ligue 1 side’s youth ranks.
Reportedly, Sochaux have already turned down a number of lucrative offers for Agoume and want to keep him until he at least makes his first-team bow.
But Barcelona are planning for the future and could be keen to wrap-up a deal quickly.
Ernesto Valverde’s men have also been linked with acquiring the services of West Ham teenager Domingos Quina for a nominal fee.
The 20-year-old Jamaican star emerged as one of the hottest prospects in European football at Bayer Leverkusen last season following his switch from Genk in January 2017.
New Gunners boss Unai Emery has been tracking Bailey throughout the summer but Roma appear to have jumped to the front of the queue in their bid to sign him.
Having lost out to Barcelona in the race for rising Brazilian talent Malcom, the Giallorossi are fixed on Bailey and could offer as much as €60million for his services.
