Arsenal academy graduate Brooke Norton-Cuffy spent the second half of the campaign on loan at Coventry, making 24 appearances alongside Gyokeres.
The England under-21 international has now lifted the lid on what makes the prolific frontman tick.
Asked if their time together gave him a sense of what Gyokeres could achieve, Norton-Cuffy told Hawksbee & Jacobs: "Yeah, 100 per cent. He was so good.
"There were teams putting two, three players on him and he was managing to beat them or find a way to score. Just creating chances out of nothing and not just skill-wise, his mental side of the game.
"You can see he's hungry, but if he doesn't score, he’s not happy. For example in practice, small-sided games if his team loses you don't want to go near him for a little bit.
"So that's just a winning mentality Gyok’s got to win things."
Gyokeres' final campaign with the Sky Blues saw him score 21 goals and add 10 assists in 45 league matches as he finished second in the scoring charts.
It was not just opposition defenders who the towering forward terrorised, though.
Norton-Cuffy added: "Vik’s powerful. He’s 6’3” and he can move, change direction quickly.
"He can run, he can beat you and then once he creates those chances, normally puts them away as well.
"It’s just a handful, just a really big handful and a good fit for us."
