Both full backs, particularly Valencia (who at some point was leading the league in crosses), have had more than enough opportunities to get down the line, but have failed to deliver a quality ball into the box more often than not. That cannot be blamed on Mourinho.
ts always funny when people weigh the quality of a teams attack in terms of counter attacking ability when in truth mos teams will not give you the opportunity often enough in open-play to make it a worthwhile scheme. Most weaker teams will simply sit deep, and deny you the space behind, which then leaves you with only set piece opportunities to counter (when the CBs come forward).
A 4-2-3-1 give Pogba more freedom than a 4-3-3 and it also gives the team more attacking talent. Ignoring the back line and DM, in a 4-3-3, you would have 2xCMs +2AM/WF+1xCF, while a 4-2-3-1 gives 1xCMs +3AM/WF+1xCF. Essentially you trade a CM for an AM/WF. Also in a 4-3-3, Pogba is essentially a LCM and plays alongside a RCM on the other side, both of them have to share the ball, and Pogba has to be disciplined and coordinated with the RCM so has not to cramp the shared spaces. In a 4-2-3-1, Pogba has the entire CM role to himself and can basically do what he wants with it. On the defensive end, how much responsibility Pogba has would depend on the amount of possession the team has and the quality of DM. The main advantage of a 4-3-3 for Pogba is that he covers less space and makes fatigue less of an issue, but then there is no evidence that it cant be managed.
Mourinho has been forced to play 4-3-3 more often simply because we dont have the requisite quality in midfield and have had to make it up with numbers. With a solid DM and better defence, we will be more daring going forward.
For me the problem of the team comes primarily two issues: the average quality of the players we have is low for our ambitions and a lot of them are adapting to a new manager, system and/or league.
I guess this is where we view things very different.
Sorry but in no way does Pogba have more freedom in a 4231. 4231 for me anyway would hamper Pogba and restrict his ability to influence the game. Add in he isn't very good defensively, often switches off and lets people run off him which is the main reason Jose switched to 433 to protect the weakness that is Pogba positionally.
Also think back to the shape of 433 in an attacking phase that has squeezed the space of the opposition team. You'll have 3 more central players, 2 Fullbacks joining in providing the width freeing up space then you'll have two CAM, or just Pogba patroling the space in behind whilst your CB's push up to join or be slightly behind that free defensive midfielder. Now Herrera can join the attack or hold back, knowing Jose he'll want him to hold back.
I think a clarification needs to be made here that AM, CAM are not the same thing as a WF or LW/RW or LM/RM
For me ok there are 1 or 2 players that hamper the team Zlatan, Valencia for example but all in all the quality is there to be better than what we have been and the problem has been Jose and his poor use of the elements he has had in the team.
If you also watch the games you will hopefully have noticed the restrictions on our Fullbacks. I refuse to believe that Valencia a former winger wouldn't attack the space or get ahead of the ball and his man unless under instruction not to do so. For the clearest evidence of this see the WBA game, for some reason he opted to sit back as he has done often this season and so has Darmian on the other side.
You mention Valencias crosses and the chance created but I've seen a heat map of his crossing and the quality of the chances created and what kind of chance they were which indicates they don't have as much weight as people have been putting on them. Over half are headers and the actual amount of really good chances is about 12. Compared to Barcas map that was littered with orange and red chances compared to our map that was all green.
Now Valencia for whatever reason likes to cross from deep. Wouldn't even call it a cross, it's a diagonal long ball it's that deep and they are floated in and of no threat. The stat is skewed by the fact we have a 6ft 5 beast getting on them just making any sort of contact.
Back on your 4231, in Joses hands and actually just life it's a more defensive formation than 433. Arguably it's not the formation that decides if something is defensive more the man wileding it. I mean Jose saying Conte was defensive shows his complete lack of understanding of the system as done right it's an abbreviation of 433 when in an attacking phase, but arguably providing even more freedom.
As for counters at time this year we would have been a far better team if we had adopted that as we have all the personal there to make it happen.
Also many teams, in this league play against packed defences but manage to carve teams open. Jose called Chelsea a counter attacking team and they seem to be top. Again an over simplification of what type of football they play by himself.
I really don't understand why you don't think we have the quality in midfield. We maybe don't have the depth but Carrick is still arguably in the top 3 DM's in the league and from the get go was the obvious partner for Pogba but Jose for whatever reason figured Fellaini was his man which was laughable. However a fit 3 of Herrera,Pogba and Carrick I'd easily put against any teams midfield in the league and feel happy with that.
Can I ask would Kante be your choice for a Dm? Even tho positionally he goes missing and in combination with Pogba would be horrendous? Actually Pogba and Griezmann are a problem for France. Because playing both you can't get either in to their best position. And neither Matudi or Kante showed they could solve the issue. Recently France have tried the guy from Lyon Talasca I think his name is and then Bakayoko got a look in with Pogba injury.France being a 4231 of course.
Actually the best formation to fit Pogba and Griezmann in for me would be some sort of abbreviation of a 352.
Anyway was intresting reading your views on football and how you interpret the 4231, however it's not something I agree with in it being Pogba best formation or even an attacking formation.
