It's a decent, quick look at our early tactics under Mourinho, with examples from our games. TLDR:
1) Our 4-2-3-1 shifts to a 3-2-4-1 in possession, which is pretty much what we see in games. Left-back shifts into the middle, Aurier moves up to the wing, double pivot stays deep, forwards push up.
2) Approach is to separate midfield and attack, to create space in the middle that forwards can drop into and then play it forward into spaces left by defenders that follow them into the middle.
3) Our problem is playing out of the press - we get into decent positions to do so, but players are making wrong decisions.
4) We also lack width on the left, since left-back moves into the middle, and Sonny usually drifts in. This needs fixing by instructing player on the left to stay on the wing, but its hard when you have a mercurial player like Sonny out there.
5) Defensively, we don't press much anymore - our Passes Per Defensive Action under Mourinho is 12.49, meaning we allow 12.49 passes per defensive action attempted. Higher than at any point under Poch.
6) We still press, but it's situational - on the flanks, and in the event of a miscontrol. Aim is still to transition quickly using pacy forwards.
7) Mourinho's general plan is to sit deep, crowd the middle and then hit on the counter. Theoretically, it's sound.
8) The issue is, players aren't covering their half-spaces behind them, and on occasion, they still move forward to press on instinct, leaving spaces behind because the lines become disjointed.
9) This leads to awful situations of players running at our defence in plenty of space.
10)
On the whole, Mourinho is improving the shape and general approach of the team - but more time is needed, and defensive/concentration issues have to be ironed out in training.
Elements of it also dovetail with this interesting (long) analysis by Spielverlagerung on the pressing traps available to a 3-4-3 -

...which basically shows how the 3-4-3 is one of the most adaptable formations for effective pressing, and is used by Liverpool (among others) to great effect. One thing the articles points out is that the 'standard' 4-2-3-1 with one holder and one mover struggles against the press of a 3-4-3, but if both of the players in the pivot sit ahead of the center backs, the pressing team is suddenly vulnerable because the striker cannot cover both pivots by himself, and thus a central midfielder must move up to cover the second pivot player, which creates a chain reaction and opens spaces in the middle.
In the video above, Mourinho's shown using a double pivot just like this, with Winks + one other to cover. That formation seems like the right one to use in light of the present pressing zeitgeist, and clearly it's something we're trying to implement.
I guess the point of all this is simple -
Mourinho knows what he's doing. It's not his tactics that are the issue here, and he's not some outdated fool trying to play 'long ball'. The guy is a genuinely world-class manager, whatever his flaws - with a support team inclusive of coaches at the forefront of the 'new wave' of tactical ideas, like Joao Sacremento.
Poch also knew what he was doing - GHod, how I miss him. But the problem was not with him, and it isn't with Mourinho. Our problem is the players. That will need to change with some relentless drilling over the summer, or whenever football starts up again.
