Mina, the Colombia centre-half who scored against Jordan Pickford at the World Cup, was a priority signing for Silva amid concern over his central defensive options.
In the immortal words of one Larry David: preeeetty... preeeeetty... pretty good.
Several Premier League sides including West Ham and Chelsea had been in the hunt for the Brazilian winger while AC Milan also expressed an interest.
Speaking about why he wanted to join, the 23-year-old told the club's website that he discussed Everton with fellow teammate Lucas Digne - who played alongside Mina at Camp Nou - before making the switch.
He cited Marco Silva as a key reason behind leaving Catalonia for England and claimed that "everyone in Portugal" knows of the 41-year-old's "qualities" as a manager in his interview with Everton's site.
'That's really why I made the choice - because of the confidence both the manager and the club showed in me'.
Barcelona followed that news with confirmation that Portugal midfielder Andre Gomes would also be moving to the Goodison Park club on a season-long loan.
However, Manchester United were put off by the excessive demands made by the player's agents, which ultimately resulted in them pulling the plug on the move.
"I did not need any convincing to come here". I have spoken a lot to the coach and I know his passion for Everton and determination to be successful.
Everton remain hopeful of completing a second loan deal for Chelsea defender Kurt Zouma, which was submitted ahead of the 5pm deadline.
