When the cost of fretting and complaining is basically zero, you can expect many people to fret and complain.
This is why internet fora are so intense and shouty. Lots of noise and no signal.
In their more reflective moments, people like Alpine know that they don't have the slightest clue about how to close deals quickly in a transfer window. None. He has no experience or insight whatsoever in his area and no one has ever decided to pay any money at all for his views or advice. Not a single person and not a single penny. Anywhere. Ever. In the history of humanity.
This is, however, no barrier at all to him commenting on the transfer window. Nor should it be. But we can just blank out such views.
If they had merit, they would be paid for them.
