Fabian Schar earned most of the plaudits, after his two goals helped Rafa Benitez's side climb out of the relegation zone.
There was also plenty of praise for another centre-back, Florian Lejeune, and striker Salomon Rondon, who led the line admirably at St James's Park.
Here's how some supporters reacted on social media:
@DanBlackwell77: Huge win today. Schar, Rondon & Ritchie all excellent. Get in!!

@TheJohnWright: Rafa has signed some great central defenders, Fernandez, Lejeune and Schar all good on the ball. Classy #nufc
@CookCookie001: That was what we have been waiting for all season. Awesome all round performance but how good were Schar and Rondon!
@Waughy72: Schar first goal. Every bit as good as Maradona in ‘86. Anyone who says otherwise knows nowt about football.
@stevewallwork: Schar will get the headlines but Perez was excellent for us today. Ckevee passing, good runs and a goal at the end. Well done lad.
@bethmann99: @fabianschaer showing @rioferdy5 how playing a CB should be done!!
@KieranBarker96: Could sit and watch Lejune mop up in defence all day, and don’t even get me started on Schar
@bellianaire: Lots of positives today, despite such a poor Cardiff team. Rondon had a blinder, Lejeune immense, Longstaff didn’t look out of Place, and what a first from Schär.
@PrimeHatem: Every player on the Pitch was great worked there Socks off Great Result
@MichaelGallon: Some great performances today but Rondon absolutely superb - best player on the pitch by a mile Great to leave SJP smiling for a change
