One-on-One Chances

The player below is one of my best players but since the beginning of this season, he has been missing clear one-on-one chances in crucial matches. At least I've watched him missed more than 10 one-on-one chances.

Now I need your advice on what to do with the player for him to regain form. I've trained him and changing drills to see if he would change but still not working out. It's not as if he's not scoring at all but missing such chances in every match mean something is wrong somewhere.

Is it that he needs rest? Please your advice will be appreciated. Thank you!https://uploads.tapatalk-cdn.com/202...a7d4afa563.jpg
