Yerry Mina departed Barcelona earlier in the month of August and joined Premier League side Everton, a deal which featured a buy-back clause in his new contract.
Barcelona sold the Colombian centre-back for 30.2 million euros, just six months after signing him for 11.8m euros, and they will be able to re-sign him for 60m euros if they believe he is worth bringing back.
However, they won't be able to activate that buy-back clause until at least 2020.
The defender can't, therefore, be taken back to Catalonia next summer, but Barcelona would be able to sign him in any of the other transfer windows during his five-year Everton contract.

It's okay to have added a buy-back clause.. as it stands, he would have till been a bench warmer if still at Barca.. Pique is aging, so by 2020, he would have matured and would come fight for a place between Umtiti and Lenglet. so I think it's right to have been sold now and buy back later if he improves better..
