A Norwich City documentary has lifted the lid on the angry meltdown the Canaries players suffered after they relinquished a one-goal lead late on at Cardiff City earlier this month.

The Bluebirds were a goal down courtesy of a Borja Sainz screamer, but Callum Robinson netted in the 89th minute before Callum O'Dowda's peach four minutes later marked a dramatic turnaround win.

While Cardiff fans and players erupted in euphoria, it was quite the opposite effect for the East Anglian players. In a fly-on-the-wall type documentary, their furious reaction in the dressing room was captured on camera.

The footage starts with Ireland international Shane Duffy marching into the dressing room before he boots a kit bin in the middle of the room and begins to lament his team-mates for their lack of game management.

"It can't happen!" he begins. "It cannot f*****g happen! How is that happening?

"F*****g hell, it's f*****g kids football. Simple decisions, get f*****g rid of it! Give a throw-in away, trying to dribble around a corner – f*****g hell, boys.

"We're not playing under-18s football. Manage the f*****g game better. It's a game of [football]. Childish!" Sign up to our daily Cardiff City newsletter here.

Duffy then slams his towel on the floor before venting for one final time: "F*****g hell! We are losing our heads, man, honestly.

"We gave them the f*****g goals."

No doubt this latest outburst from Duffy will only add to the catalogue of moments for which Cardiff fans will remember him. The defender famously scored two own goals and was the recipient of a red card while playing for Blackburn in the 2016/17 season against the Bluebirds.
