The 26-year-old fan-favourite has impressed of late for Chiefs, notably scoring in the 3-0 win over AmaZulu in the Telkom Knockout on the weekend and providing an assist to Bernard Parker in a recent 2-1 league win over Mamelodi Sundowns.
Komphela has revealed Ekstein's teammates have been providing constructive criticism to help the late bloomer deliver on his potential.
“With regards to Ekstein, George Maluleka will tell you, they were always on his case. There’s a couple of things that he still needs to do to complete his game to be a threatening player,” said Komphela.
“But confidence-wise, he’s grown. One thing that I can disclose which is apparent, is upon receiving the ball he is getting forward, effecting the game.
“Previously Ekstein will play square, back without wanting to take a risk. But I think now he’s wearing a risk cap and it’s paying off.
“An Ekstein oozing with confidence, with the technical ability that he’s got put in the right places with the tactical approach, is a big threat.
“Operating in small spaces... I don’t know how this guy thinks because unfortunately we are football people, we think with our feet. He’s very quick with calculations. He’s more of a genius.
“He gets the ball and with no time he just twists things. I hope he’ll get to the level where he’s consistent throughout to be complete, even with the stuff that he needs to rectify.”
Chiefs will meet Chippa United in the quarter-finals of the competition.
