Not commenting on players here, or trying to debate whether we are objectively playing "good" or "bad" football (that much should be obvious).
Which is a difficult preset to do... Because it is next to impossible to judge a plan without considering the execution of that plan.
My sole concern here is to highlight some of the systematic problems with EtHs setup. Feel free to add your own, there are loads!
1. The gaps between our players are huge. This makes it difficult for the man in possession to find a pass, and it increases the likelihood of turnovers.
Definitely a big problem I agree. But to me, this probably isn't so much the positioning itself but the organisation - the match is in motion and as the team moves, we are losing our structure. It is something, that should go away over time. But for such synergies to form, we also have to stick to one system...
1.1 Since the gaps are so big, when we do turn the ball over, the opposition can cut through us with one incisive run or pass because there's huge space to exploit.
Thats definitely a problem. But at the same time, our wide positioning is also stretching the opposition to create more space in the centre of the pitch. It isn't an ETH specific thing but very common. Two sides of the medal, risk or reward. But I agree with you, too often it comes with no reward for us.
1.1.1 When Pep was asked why he prefers short passe, he answered "because we lose the ball less, and when we do, we're well positioned to immediately win it back". In effect, we have achieved the exact opposite. Making the passes harder / higher risk AND putting us in a poor position to recover.
The tighter it gets, the higher the technical requirements on your players. So yeah, Pep obviously goes for this and in principle it is right, but when done correctly, our long balls are a good way of stretching the opposition. Especially one that tried to stay close to each other for short passing.
2. Our CMs are asked to push on, so whenever they receive the ball it's generally with back to goal and a defender up their backside, limiting their options and increasing the likelihood of turnovers. When you watch the likes of Mainoo, Mount, Bruno etc...they're almost playing like a CF...receiving the ball with a defender all over them like a rash and facing their own goal.
Thats part of the story - the wide players keep their width to stretch the back line - the striker occupies the CBs and the other attacker is supposed to keep the oppo DM busy - by pushing two 8s up, it should overload that area. The idea makes sense but for it to work, it needs good organisation and suited players. Without those, the risk-reward-ratio can quickly turn against you.
3. There are no overlaps or underlaps because the full backs tuck inside, to do....I don't know what.
Thats also a pretty common thing these days. Most teams when in possession form a back three and one part from that backline will start supporting a different are on the pitch. The idea itself makes sense - the question is whether our players are suited for it.
4. Players consistently pop-up in odd positions. We occasionally create overloads, but when we do it's usually Dalot in a pocket or someone equally poorly equipped to pick passes in tight spaces.
I agree, I think, we are overdoing the fluidity part to a certain extent. Fluidity makes sense but I feel for some of our players it might be too much too handle at the minute, especially given that it is a collective thing - so even if one player does his part, he could still look awful when the next player doesn't.
5. Where is our defensive line? We don't play a high-line, which contributes to the first problem on the list....but we don't play a low-block either...it's just nothing. It's kind of a "worst of both Worlds" between low block and counter and high-line and press. It's almost like a bizarre middle-block, counter-attack system.
This has always been a spectrum. I agree though, for the intensity our attackers press at times, the line should be higher. But for a long time, we had players there who were very uncomfortable pushing up. Which lead to that donut phenomenon - where the attackers push up while the defenders only push up hesitantly leading to a hole in the centre to form to bring shame to every player who is left there to take on opposition players at speed, in numbers. Mostly alone. Again, it is a risk-reward thing but it is something, that takes time to get instilled.
6. The long ball tactics encouraged by EtH create chaos, which causes turnovers...which are exacerbated by problem one.
We definitely overdo it. But at the same time, I always feel that ETH (and many other coaches) happily surpass the midfield by simply making long passes, so it isn't a ETH specific thing but I agree, it would be better to get that under control.
7. We like to lure the press on, but we're always trying to pass out 4 vs 4 or 5 vs 5 because half our team are standing on the halfway line. This is just asking for trouble, and we usually get it. You want to create a "defensive overload", which is why teams started buying ball-playing GKs...but we don't and are always playing out with equal number defenders vs opposition pressers...and this means passes have to be inch perfect.
I think, this is mostly down to your problem no. 1.
8. We play inverted wingers but without overlaps or underlaps, you really want your winger to be attempting to beat the man on the outside...which they're reluctant to do...because that leaves them crossing with their wrong foot. Surely we either need a natural left / right footer running beyond the wide forward OR they need to play on their natural side? The end-result is nearly always players coming back inside into trouble and us losing the ball.
Not sure they are really inverted given they are instructed to hold the width. Issue with them is, we employ no wingers there but wing forwards who aren't looking to swing in crosses but try to get at the end of things. Add to that our fullbacks stand out for being unproductive in terms of exploiting space in the last third and you got what we see there so often.
This sounds awfully as if I am trying to rectify ETH. not my intention but some of the things you observe aren't any crazy ETH specific things but rather common things that simply fail for various reasons for us. Be that some players with very specific skillsets (that aren't the most modern), be that a rather subpar overall workrate and often times lacking intensity, be that the apparent lack of any form of organised pressing structure for years which set our players back. ETH has now to pay off the debt that the previous decision makers amassed. Which doesn't mean, that he is a poor victim and shouldn't be judged - he should - but nobody should fall for the illusion that the formentioned issues would simply go away as soon as the name of the manager changes.
