Speaking after the move was finally confirmed, Fernandes said: “My love of Manchester United really started when I used to watch Cristiano Ronaldo play and ever since then I have been a big fan of this great club.
“For me to now play for Manchester United feels incredible, I have worked hard to get to this moment and I can promise the fans that I will give everything for the badge to help bring us more success and trophies.
