This has nothing to do with Lingard himself: he is a useful player off the bench but not in this situation imo. We're taking off our only forward remaining: at least introduce a like for like replacement. Someone who can be a genuine threat not just up top but on the counter as well. Lingard can score in his own right but Martial just appears to be the more natural choice in this situation. Just been weird subs for the most part on Ole's part, from my point of view.
