That was the 17-year-old's fifth appearance of the season and Brunt believes the fans are starting to see the potential the academy product has after he also made three brief cameos towards the end of the last campaign.
Brunt feels Leko is unique when compared to any other player in the West Brom squad and is confident he will get better as he gains more Premier League experience.
“He’s got unbelievable ability, he can go past people, he’s strong, he’s quick,” the 31-year-old told the Express & Star.
“He needs to get first-team football to get that experience and become a little bit more streetwise in the Premier League. That’s probably the best way you could put it.
“The first couple of times he went past a guy - he took too big a touch and then next one he fired it across and we hit the post.
“If he can bring that end product to his game he’s going got be a top player for us to have to throw him off the bench if you’re chasing a game. He’s a weapon and something different to what we’ve got at the minute. Credit to him, he did well.”
