Imo, Barker's higlights reel would be as good or better than Sancho or Diaz, at the same stage in his career. They each have different attributes where one is better than the other but Barker produced literally scores of absolutely stunning moments & some of it hasn't been bettered yet, from what I've seen.
If Diaz is still n he reseves in two years, he will probably be labelled a failure with an attitude problem on here & then shipped off to Barnsley, fat & depressed.
Sancho & Diaz are reaching that moment where hey are too good for this level but not necessarily able to play every week in a lower league team. They need help from our manager or from another manager, to help & inspire them to the next level. Something none of our previous generations has had as yet.
