The content of the messages is fine. Standard scouting report chat, Tame stuff.
It was pretty sloppy to leave an open screen whilst you know people are directly in view of it but it should just be treated as a lesson learned for the future.
Watford will 100% try and fan the flames now, and so they should. But from my eye there wasn't much in those messages that hasnt been obvious about them for a good few seasons. They always strike me as a collection of players rather than a team. occasionally they may have enough individuals turn up to win but mostly they just seem a bit soulless and uninterested.
Will add I'm quietly impressed by Mark Robins emoji use
