The 21-year-old centre-back has been nothing more than a bit-part back-up player ever since moving to the Emirates in a surprise transfer from Bolton Wanderers last summer.
But he was called upon this evening at the Riverside, with Arsene Wenger freshening up his lacklustre side and opting for a three-man back-line.
He might be a lot younger and have a lot less experience than his team-mates, but Holding’s performance displayed wisdom beyond his years – and seems to have won over a lot of supporters:

Rob Holding looking like a great centre-back so far. But how long will it take before he becomes 'Arsenalised'?

Get yourself a man like Rob Holding. Will always back you up, remain calm, and has a classic haircut.

Rob Holding is world class no lie.

World class? The new Tony Adams? It’s not like Arsenal fans to go a bit over the top on social media, is it?
Regardless of the comments, Holding did perform extremely well, and we’re not the only ones who’ll be deeply shocked if he’s not selected for Arsenal’s FA Cup semi-final with Man City next weekend.
What do you think?
