Mina stood out at the World Cup for Colombia, who exited on penalties against England on Tuesday evening, but his future at Barcelona has not been affected by his displays in Russian Federation.
Mina scored three goals in three appearances in the finals, including a stoppage-time equaliser against England on Tuesday as Colombia were eventually knocked out in the round of 16 on penalties.
Also adding to Mina's uncertainty are Barca's plans to sign Gremio midfielder Arthur, which would require freeing up a place for another non-EU player.
He added: "In my head right now, I am thinking about returning to Barca".
Although the centre-back played well in Russia, Barcelona are still planning to let the player go and to replace him with Clement Lenglet.
"Now's not the moment to talk about my future, but the World Cup has helped me rediscover myself and reaffirm myself as a footballer".
God gave me my talent. After that, I'm always calm and I trust God.
To earn a move to the Camp Nou, you have to have something special and that is certainly the case for Mina, a 23-year-old who already has 15 caps for Colombia.
According to the report, the Catalan giants were initially keen to send Mina on loan to Everton, but could be willing to sell him if they are granted a buy-back option.
That's because Barcelona worked a £90m release clause into Mina's contract when he arrived at the club.
Liverpool's need may not be as strong, but with Dejan Lovren and Joel Matip struggling to assert themselves as partners to Virgil Van Djik, Jurgen Klopp may be tempted to sign Mina as he looks to build a title challenging defence.
