Barcelona have completed the signing of Palmeiras defender Yerry Mina, La Liga News UK understands.
The Catalan side will pay £8.5m for the centre-back, who will remain on loan with current club Palmeiras until the end of the 2017/18 European season.
Club bosses have grown increasingly concerned by the defensive frailties on show against Real Madrid in the two legged Super Cup tie and wanted to act to reassure fans.
Marca have also reported a deal, which would see him join the club in July next year.
His arrival would provide healthy competition for Gerard Pique and Samuel Umtiti, whilst he would replace Javier Mascherano, who is playing less and less.
Mina is a promising young talent and one of the brightest players to feature in Brazil in recent years, attracting intense attention from Europe.
At 195cm, he would add some much needed height, and whilst he lacks experience in Europe, he does have six international caps to his name already despite his young age.
Currently recovering from a broken metatarsal, Mina is sidelined until mid-September when he will hope to return to aid Palmeiras to secure a place in Copa Libertadores, with the side currently fourth in the Brazilian Serie A.
