Gurgen But we need him to contribute so we need to get behind him and help him build some confidence
That is essentially what it is. When players keep getting injured they lose confidence and their rhythm. As a result they try to hard or force the issue. Since his knee injury he has not had an injury free run and I think that has massively knocked his confidence.
Look at Havertz a year ago, many on this forum wanted him out and now none of them would drop him.
