The 31-year-old has been a good servant for the club since moving to Newcastle in 2018. It is no surprise that the Magpies want to hold on for another season.
The player seemed delighted with the decision as well and he took to Twitter to share his reaction.
He tweeted: “Really happy to extend my contract. Hard work pays off.”
Newcastle fans seem very happy with the decision from the club as well.
Fernandez has done well for Steve Bruce so far this season and he will be looking to help his side finish the season strongly now.
