Don't disagree with anything you say in relation to DCL's actual play - good link work, still improving, at least potentially a useful squad player, maybe will even be a good scorer one day. I do disagree a little with what you said about people on this forum, however. There is a significant proportion thinking he is the long term front player and should be accepted as he is, or given more time as a regular starter to become a good goals man.
What some of us think, is that DCL, especially in view of the paucity of other potential scorers in the side (Richarlison excepted), should be replaced in the starting 11 if possible by someone more reliably slotting chances and capable of making his own. Not really much separating the views of most people, but really causing a lot of feeling.
