I’m not criticizing Poch, there’s no one else in the world I’d rather have. And I’m not saying the late subs are a problem that’s holding us back - what I’d really like is to better understand it.
I’d hypothesize that we’ve made far fewer subs than the average PL club. I’d also hypothesize that our average 1st/2nd subs appearance is probably somewhere around 8 minutes later than the average, probably across the board even if you parsed our specific scenario (i.e. trailing by one goal away). I’d say that the trend is strong enough that it likely discounts any idea that Poch gets caught out without having plans A-Z prepared and players sufficiently warmed up for those.
It’s seems likely to be something ingrained into his coaching ethos, the late sub. I haven’t read his book, not done a deep dive for Poch comments on coaching strategy, but if there’s anyone that could shed light on that I’d love to understand it. It’s fascinating because to me it does seem like a specific ideal that runs somewhat against popular conception.
I have read the book. One comment that springs to mind is the faith Poch puts in his XI players and his coaching strategy. Any sub will disrupt the team/shape so I guess it's not something he eagerly looks to do.
