I respect your opinion HBIC but read your post back...the tactical chicanery needed to coax something even remotely resembling a useful performance out of Lo Celso is worrying.
Let me first reiterate: I have no love for our obsession with 433 as I think it instantly negates half our outfield players and also tempts Kane to play as a midfielder instead of his actual position.
But being as it is that we're infatuated with the thing, where does Lo Celso fit in?
RFW? Son's position.
LFW? Useful in the press but can't beat his man and also can't cross. So it's cutting off our nose to spite our face. Also I think Lucas (since last season) can harass just as well as him and while the brazilian's delivery isn't much better, he is definitely better at beating his man.
RCM? Skipp or Hojbjerg surely better in this role.
LCM? Probably where I'd play him tbh but it hasn't really happened much in 2 years.
Either way, I still think our strongest XI using a 433 doesn't include him. I'd use attacking FBs for width, a midfield base of Skipp and Hojbjerg and deploy Tanguy just in front of them, giving him the freedom of the pitch. Then Son, Kane and Lucas in front of that two tiered midfield.
You've got it back to front, since deploying Lo Celso as a high-presser is the tactical chicanery required to stop Ndombele sending passes directly to opposition midfielders
And this is the point: most clubs need tactical chicanery to get something out of all their players, look at clubs like Southampton and Swansea who had a few seasons of playing way above expectations and getting promptly dismantled by a handful of clubs (usually Liverpool) and yet the majority of the players never came close to replicating their form elsewhere, all because the system was custom made to get the absolute maximum from those players
In our case there's definitely some alchemy needed to get more out of certain players, for example we need somebody pressing higher up the pitch in order to give Ndombele the time and the space to get a dangerous pass through to a teammate because otherwise he'd either be an exotic-named Harry Winks playing percentage plays because he can't find the space or a liability who tries to force the pass through anyway, just as we need somebody between defence and attack to ping the ball between the lines for Sonny to break into the box, just as we need Hojbjerg to drift out wide so that there's somebody covering when Reguilon heads up field
The issue is that not only are we lacking a Dembele who was so good at creating pockets of space through the centre that several of the team could exploit simultaneously (i.e. opening a channel for Eriksen to send a ball through, creating a pocket for Dele to run into, drawing in defenders allowing Walker or Rose to overlap) but we've also lost our press resistance so our midfield can and often has been overrun, and it's the latter which has been particularly destructive since the back end of the 2018-19 season because since that period we've either seen our midfield get overrun or effectively surrendered for large portions of a match, and as last night demonstrated once we lose momentum in a match we can't regain it
And this is where Ndombele is problematic, because he's the perfect example of a player who can be fantastic when we have momentum behind us, but when we don't he's a liability because he's not tracking back when we don't have the ball and also liable to misplace a pass and give the ball away when we do have it, both of which were on display yesterday evening - and the only way he won't be? If we have an effective screen ahead of him, even if that screen nerfs the player who is having to perform in this role
In terms of where Lo Celso fits into a 433, however, it is readily apparent where: as a RCM
Nuno's system does seem to have been designed around a marauding RW, drawing obvious and/or lazy comment about Adama Traore, and because of this we need a player in midfield who can not only get the ball to them reliably but also get stuck in if we don't have the ball, and Lo Celso is best positioned for that - and that isn't just wild speculation either, considering the one time where Aurier looked absolutely lethal during Mason's time in charge last season was when Lo Celso was the RCM, as he was knitting the play on the right side together not just with passes out to Aurier and up to a deep-lying Kane, but he was also making himself available for the return pass - something which can't be said for Hojbjerg against Rennes last week, as Doherty was often passing inside to nobody as Hojbjerg was flitting between box-to-box one passage of play and a deep-sitting CM the next
The real question is who the LCM would be, because there's three options
Hojbjerg, who combines well with Reguilon - but that means Skipp plays, meaning we have two pragmatic midfielders in the three
Ndombele, who makes the ball move quickly and is direct when passing - but can often be a passenger when we don't have the ball
Dele, who works his bollocks off - but there's no real end product to this at the moment
This is ultimately the issue, as the most balanced midfield three we can play at the moment is Skipp, Hojbjerg and Lo Celso - but there's no denying that trio lacks dynamism going forward while also not having the strength to be a rock solid mid block for when we don't have the ball, and that's something that won't be sorted until 1st July 2022 when Sarr officially joins us, while also explaining why players like Nahitian Nandez and Weston McKennie were so strongly linked late in the window as they're both closer to Hojbjerg than Ndombele
