Middlesbrough overpowered Norwich with a clinical display to keep alive their faint hopes of automatic promotion.
Cameron Archer teed up Aaron Ramsey to tap in the opener against his former side before Hayden Hackney's half-volley made it 2-0 with the first of four goals in 10 minutes before the break.
Archer slotted in the third and then promptly snuffed out the brief hope given by Josh Sargent's finish by punishing more sloppy defending with a powerful finish.
Chuba Akpom tapped in a fifth soon after the break thanks to Archer who added a second assist to his goal double as Boro moved above Luton on goal difference into third.
