"Tired? At 26 years of age, I can't be tired," said Fernandes.
"If I am tired now, when I get to 30 or 32, I won't be able to play or I will play one game out of every five. No, I am not tired."
"The coach knows what is better for the team and against Liverpool he chose to play with Donny [van de Beek] to give some freshness to the team," added Fernandes.
"It's fair enough because Donny is training really well, has been important for us and will be more and more important in the future."
