The Leeds head coach has been discussing the winger's display v Brighton.
Earlier this month, the German said he felt Botaka looked promising but that he needs to work on his end product.
And the Leeds boss said the exact same thing after his side's 2-1 defeat to Brighton on Saturday afternoon.
Rosler told BBC Radio Leeds: "I think there is a lot of potential. But I wish for more end product. He brings himself into very good positions. He's dynamic, exciting. But then we need the final ball. And that's not only for Jordan."
One statistic sums up what Rosler is saying: the fact Leeds created just two chances all game against Brighton, compared to the away side's 13.
That's despite the Yorkshire side enjoying far more possession than usual against Chris Hughton's men.
Of course, the fact Rosler has once again re-emphasised the same message to Botaka suggests it's up to him as his coach to get more out of him in terms of a final product.
On this occasion, however, the international break got in the way, with Botaka in action for his country. But, in the coming weeks, it's clear what needs to be worked on in training...
