Fernandez joined Newcastle in the summer from Swansea, and has been thrown straight into the starting lineup by Rafael Benitez.
“We have a couple of games against teams who are maybe middle of the table now. It’s no excuse, but in these five games we knew it would be very difficult, against top teams," he told 'nufc.co.uk'.
“But we’ve approached them well, we’ve played like a team, but we didn’t take anything. Now we need to start taking points, because that’s what we need.
“We need to analyse the good things and prepare for Crystal Palace away. We can go there and win the game, so we need to be ready, be focussed and positive.”
