Mourinho was asked about the Portugal international's impact at United since arriving in January, to which he replied: "Bruno came in, was fit, played very well, improved the United team and also proved to be a great penalty taker, one of the best in the world, because he had about 20 to score."
"I honestly did not feel stung," Fernandes told A Bola.
"I feel that I am a good penalty taker and nothing more, I understand, but what I take from his [Mourinho's] words, because I'm a very positive person, is that he said I hit penalties well.
"It is a reality, not least since I arrived at Manchester United.
"I hear people saying, ah, he only scores from penalty kicks… but a little while ago, I saw the statistics and, except for penalties, only Kevin De Bruyne has a higher involvement in goals than me in England when it comes to midfielders."
