This. In 18 months, I have never, NEVER, seen him mention one word about tactics.
Slot, within 5 minutes of him arriving at Liverpool, was happily talking about his back 4 positioning change at half time against Ipswich to exploit the press, explaining to the reporter how their positioning was important for when they lose the ball.
Pep: look at Pep's eyes light up when he gets asked a tactical question by a reporter. He's so obsessed with this sport he spends 10 minutes at the end of games chatting to opposition players, presumably about what they could have done better on the pitch, or what he liked about their game. He lives the sport, he lives tactics, and you can see that in the results he gets.
Arteta: was handpicked by Pep to be his coach because he's just as obsessed with football. Famously they spent an hour discussing tactics after one of the games when Arteta was still a player. And again you can see that in what he's done for Woolwich over the past 5 years.
Go through the list. Emery, tactics obsessed, turned Villa from relegation into CL regulars. Howe, already a hugely accomplished manager having taken Bournemouth up 4 divisions, but he wasn't satisfied with that so in his sabbatical after Bournemouth went and studied under Simeone - because he's a smart, curious man who loves the sport and likes learning. Since then he's taken Newcastle from relegation to the CL.
Smart men, interest in the game, deep thinkers about the sport, and they get results.
Then you have our muppet. Never utters a word about positioning, tactical adjustments, pressing, structure, never says a single insightful thing about the sport he spends all day watching. Just the same old guff about effort, being together as a team.
Has he ever made a good tactical change in his life, a substitution where you've felt "yeah, this guy really gets what he's seeing on the pitch"? No. It's "oh we're losing, better sub our entire midfield" - something no competent manager has ever done in the history of this sport as far as I'm aware.
And Dier famously said he doesn't do any tactics. People wrote this off back then - is anyone surprised about it now?
It's becoming eminently clear this man is a pub level manager, who doesn't think deeply about this sport one iota. He'd be on a building site if he wasn't involved in the game. He's a charlatan of the highest order. And is absolutely sinking this club right now, and has hoodwinked half the fanbase in the process.
