He told Sport1: "Both I notice and Jadon notices that he is not yet at his absolute best, but that is completely normal for us. We knew that.
We know that he is capable of reaching this maximum very quickly. The question is, is it possible to do this every three days?
But we see Jadon perform an action in every training session that shows his extraordinary talent.
We see how diligent he is with the tasks and how hard he works on them."
