"Donovan took his chance on Saturday with both hands.
He led the inexperienced Owls defence a merry dance and was brought down for our penalty - but also did not neglect his defensive duties, tracking back to make a crucial tackle early on," Westbrook said.
The supporter expressed optimism about Donovan's future, saying, "If he carries on like this, we have a real star in the making on our hands."
Donovan previously reflected on his footballing journey, noting that he started playing at age seven and initially played as a centre-back before transitioning to an attacking role.
"I used to be a centre-back, I used to love dribbling out from the field.
I spent one season there, then I just got picked up by the Blues," he said.
Having made his Championship debut at just 16, Donovan said he thrives under pressure in front of large crowds.
"Since I was young, I loved pressure. I loved playing in front of people," he said.
He described the emotional boost he gets from fan support, saying, "When I see the fans cheering when I'm coming on...
