He told Sky Sports: "I was upset. As a penalty-taker, you have your own routines, your own things that you do. It upset me because the referee didn't apologise. That is what triggered me in that moment, but that's not the excuse for missing the penalty. I had a very bad hit on the ball. I put my foot too under the ball, and that's why it ended up going over the bar."
Meanwhile, United head coach Ruben Amorim said to BBC Radio 5 Live: "In the first half we were there, we missed a penalty...Fernandes has so much responsibility with him that I felt the lack of joy [when he missed] and he was thinking in the past. Now we have to move forward no matter what happens."
