Mina is reportedly close to a big-money move to Everton.
The 23-year-old starred for Colombia at the World Cup, even scoring for his country against England, and Spanish newspaper SPORT claim Everton are closing in on a deal to land the defender for a fee of £28.5million.
Mina is likely to be available for a transfer after featuring just six times for Barcelona last season, with the likes of Gerard Pique, Thomas Vermaelen and Samuel Umtiti above him in the pecking order.
Despite the links to Everton, Mina posted on Instagram in his Barcelona training kit with the caption: "In what I like the most", perhaps suggesting that he wants to remain at Barca.
Everton desperately need a centre-back this summer, after loaning Ashley Williams to Stoke City and selling Argentina international Ramiro Funes Mori to Spanish outfit Villarreal earlier in the summer.
It leaves Marco Silva with just Phil Jagielka, Michael Keane and Mason Holgate, with none of the three impressing last season. A new central defender is a must before Thursday's deadline, but Mina's Instagram could come as a blow.
