Barcelona can buy the centre-half back for around £30m if he does well at Goodison but, for now, he is an Everton player.
And Mina was followed to Everton by Barcelona teammate Andre Gomes, with the Catalan club confirming his move on an initial season-long loan with a fee of £2m.
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.
Fulham also made some potentially smart signings, with Andre-Frank Zambo Anguissa and Argentina worldwide Luciano Vietto arguably chief among them - the latter joining on loan from Atletico Madrid with an option to buy.
"Everton is historically the fourth most successful club in England", said Bernard.
Everton and Fulham stole the show on the Premier League's transfer deadline day, as both clubs welcomed several eye-catching signings. "This is a great opportunity for me", said Mina.
'Marco's words helped me a lot because having a coach who believes in his ideas is important.
'I know about Everton's players and I look forward to being able to play with my new team.
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.
