I'm not sure why you've decided my opinion is valid only if I'm prepared to harass someone outside their place of work.
If all criticisms are only valid if delivered in person then I'd better book some time off work to find Heckingbottom to tell him I disagree with some of his substitutions, Fleck to ask him if he's holding back because of health concerns, Baldock to remind himself to relax when he receives the ball and Egan to drop a couple of yards deeper so he can run onto a clearing heading rather than getting caught under it.
That doesn't mean I think the substitutions Heckingbottom makes when his online shopping arrives are poor, or that Fleck takes his time when climbing the stairs at his house, or that Baldock runs around chaotically when playing fetch with his dog, and definitely not whether Oliver Norwood struggles to get himself out of bed in a morning because it's raining.
My opinion is based on what I see, in the flesh, and my experiences of these players. I have an opinion because I'm interested in their performance. I form that opinion because one exists in context of the other.
If you're happy to perpetuate a straw man argument because you find my opinion uncomfortable I'm ok with that. I've asked to be corrected twice but instead you've called me a coward twice.
If it helps, yes I would say it to his face but I wouldn't enjoy it and it would be inappropriate.
If it doesn't help, it's worth reminding that you're registered on an open forum.
