Speaking to Sky Sports, Fernandes said: "It's really easy when you don't get results, when you don't get the performance that you start losing belief on everything you've been doing but I think that was one of the good things we had as a team - we kept the belief on what we are doing, on what we've been training and where we want to go as a team, where the staff wants us to go as a team, what we want to improve as a team.
"And that is what is giving us now some more credit because we've been doing the same things that people probably will think like, 'oh, the manager has to change this back three or back five, it doesn't work. We need to go back four. We need one more striker.'
"You know, every time you lose or every time something goes wrong, everyone has an opinion about what you should do differently. But obviously the manager has his own idea and we understand. What we do really understand as players at the moment is that he really believes in this. So there is no way that it makes you not believe it."
