Fernandes scored a penalty on Sunday, but Manchester United gave up their lead twice during the game.
"We're improving, but it's not at the level we want it to be," Fernandes said.
He acknowledged that football is a game of passion, and things don't always go as planned. Fernandes noted that the team looked a bit lazy during the game and needs to work on that.
Fernandes also touched on the team's financial situation, stating that the club is doing its best to improve the squad. He believes that the team needs more competition and quality to help players step up their game.
Fernandes emphasized the importance of attention to detail and the need for a winning culture at Manchester United.
"It's every detail, every small detail matters," Fernandes said. "At this football club, you can't make mistakes on or off the pitch, because it's a big club with a global following, and you get punished for it."
Fernandes wants the team to bring back the winning mentality that was once synonymous with Manchester United. He acknowledged that the club has made efforts to improve facilities, staff, and the team, but more needs to be done.
"The fans are paying more for tickets, and we appreciate their support," Fernandes said. "Now it's up to us to repay them with good performances on the pitch."
