The 23-year-old has been linked with a move away from the Nou Camp over the last few weeks, and although Everton were among the initial suitors, it seemed Manchester United had jumped ahead of them in the queue for the Colombian.
Barcelona’s refusal to move from their valuation of £35million was also said to be a sticking point for the Toffees.
However, according to Goal, the two clubs have now agreed a deal for a £29million transfer, despite late interest from Lyon for a player who made just six appearances for Blaugrana last term, but starred at the World Cup for Colombia.
Mina returned to training with the Catalan side on Monday, though it seems he is now headed towards the exit door, just six months after arriving at the club.
Chelsea star Willian has insisted he is more than content to stay at Stamford Bridge.
Following the Community Shield defeat to Manchester City at Wembley, the 30-year-old Brazilian once again placed on record his willingness to continue his career in west London.
However, the midfielder did hint that he needs more clarification from the club over whether or not they want him to stay long-term.
Willian has been linked with Barcelona all summer long but the chances of a move to the Camp Nou materialising now appear slim, particularly after Blaugrana clinched a deal for Arturo Vidal.
The Belgian midfielder, who was part of Roberto Martinez’s World Cup squad which finished third in Russia, has just 12 months remaining on his Spurs contract and it has been suggested he could end his six-season affiliation with the Whites.
But Dembele seems content enough to remain and fight for his place in Mauricio Pochettino’s midfield, so much so that he apparently rejected the opportunity of a move to the San Siro.
The 31-year-old has suffered with injury problems in recent seasons but his experience is still a key asset for Spurs.
