Premier League side Everton hold a serious interest in the Colombian and are hopeful of adding him to their ranks before the transfer deadline on Thursday.
It promises to be an exciting few days at the Camp Nou on the transfer front with Barca doing everything they can to secure the capture of Manchester United midfielder Paul Pogba and a host of fringe stars expected to move on to pastures new.
However, with just days remaining in the window for English clubs, players looking for a move to England must make haste if they are to beat the deadline.
Barcelona duo Mina and Marlon Santos have both been linked with Premier League switches this summer and both trained apart from the rest of the squad during Tuesday's open training sesison for the media.
According to the club, the pair were undergoing individual work, but many onlookers have opted to see it as a sign that the pair could be moving on in the coming days.
Mina appears set to join Everton for a significant profit on the fee Barcelona paid for his sevices just seven months ago.
Marlon, for his part, has an offer on the table from Sassuolo, having seen a move to Southampton put on the backburner after the secured the capture of Borussia Monchengladbach defender Yannik Vestergaard earlier in the window.
