The Leeds boss has been discussing the young winger.
The 22-year-old was signed by Uwe Rosler but the German himself even complained about Botaka's lack of end product before he was sacked.
Now, the young winger is failing to break into the Leeds first team and, despite acknowledging his hard work, the Whites boss feels the wide man just isn't doing enough at present.
Evans told reporters: "The kid’s working hard but working hard isn’t enough on its own. I can’t fault his endeavour and I can’t fault his desire. I know this chance means so much to him.
"But on top of all that there has to be end-product and he has to deliver performances. He’s had two or three chances and quite simply he hasn’t shown the ingredients which tell me he should be on the pitch.
"I’m not saying he can’t get better or won’t get a look-in because I will give players a chance. With Jordan, I’m not seeing the quality or the end-product I need to see. It’s that simple."
It's a firm warning to the 22-year-old and it has even more resonance following Mustapha Carayol's excellent Leeds United debut.
The winger scored and generally impressed against Rotherham in the FA Cup, while Evans went on to praise Stuart Dallas and suggest he and Carayol compliment each other.
As the Scot says, there is nothing stopping Botaka from getting into the team if he can up his game. But he clearly hasn't yet produced like fans thought he would when he signed.
Botaka has pace and skill but, right now, several other areas of his game are lacking.
