Norwich City boss Daniel Farke could not hide his frustration at Greek attacker Christos Tzolis after he appeared to overrule Adam Idah to take a penalty against Liverpool on Tuesday night.
The Canaries were 1-0 down in the Carabao Cup third-round tie when Tyrone teenager Conor Bradley fouled Dimitris Giannoulis just before half-time.
The referee pointed to the spot, and Ireland's Idah picked up the ball. However Tzolis took it off him, only to see Corkman Caoimhin Kelleher save the effort with his legs.
Afterwards Farke would not explicitly say that Idah was the man designated to take penalties but he did not pull any punches when it came to his assessment of the incident.
"He's made this mistake once - I will make sure he will never ever make this mistake again in his whole career," said Farke.
"He has apologised so it is okay. When you choose to work with young players, [you] accept there are mistakes. Believe me, after our conversation it will never happen again.
'No, he was not [the taker] on the paper. It was a big mistake. Listen, young guy, he helped create it, unbelievable emotion and excited. This is what happens. Young players, they take the wrong decisions.
"I’m a bit annoyed. None of my other players were aware he should take penalties again. I love this guy, he will be an important player for us in the future."
Tzolis joined the Canaries from PAOK for €12m in August.
Just before he moved, the wideman came off the bench against Bohs at the Aviva Stadium in the first leg of their UEFA Europa Conference League third qualifying round clash, which the Gypsies won 2-1.
