There was a detailed analysis yesterday on Sky of Glasner’s preferred methodology together with video examples of teams he has previously managed.
The system involved 3 at the back with the 2 full backs pushed further on, 2 central midfield players and 3 forwards playing within a few yards of each other looking to interlink quickly when in possession.
I’m wondering if this suits our current squad,
1) Mitchell doesn’t seem to have the skill set to play left wing back
2) Huge demands are placed on the 2 central midfield players and in many games there are risks of being outnumbered in there by many Premier League teams.Wharton and Lerma noticeably tired last night around the 70 minute mark.
3) Where does Eze fit in to this system? He doesn’t defend enough to be one of the midfield 2 and has looked uncomfortable when pushed into the front 3.
4) The system involves the 3 defenders on occasions aggressively pushing forward to supplement the midfield winning the ball higher up the field.I would have doubts that this would suit Anderson, Ward and Richards although Guehi could probably adapt.
Anderson and Ward don’t have the pace to recover if they lose the ball and Richards has looked uncomfortable when stepping into midfield.
5) The system requires the front 3 to work really hard pressing from the front and, again, I’m not sure it suits our current players.

In conclusion I think I think it’s too early to make the transition to the new system with the players at our disposal unless we make tweaks e.g 352 where Eze plays as the most advanced of 5, but then where does Olise play?
If you retain the 3 up front you have to shoehorn Eze in one of the roles.

This is an opinion as is obviously open to debate, but I think there would be teething problems if we move to rapidly to such system until we have had type to refine it and have the right players.

3-4-3 I can see Andersen being the ball playing centre half. Similar to what Conte did to Luiz at Chelsea.

GK (Johnstone or Henderson) it is a toss of the coin I wonder who he will pick

LCB (Marc Guehi)
CB (Joachim Andersen)
RCB (Chris Richards)

LWB (Tyrick Mitchell)
DM (Adam Wharton)
DM (Jefferson Lerma)
RWB (Daniel Munoz) playing RWB we will probably see the best of Munoz very good going forward

CAM (Eberechi Eze)
False 9/ST (Jordan Ayew)
CAM (Michael Olise)

With Olise out for a long time Ayew will probably play in Olise's place and that will leave either Edouard or Mateta playing up front. Can Edouard do well under Glasner?

I understand what you're saying about 3421, but the analysis last night focused on Glasner and 343 with 3 front players pressing closely and interlinking quickly.
The point I'm making is that we would have to tweak the system to properly accomodate Eze.

any decent managers will first see what resources they have and pick a formation that best works for them.

That was deBoer's issue - he picked the formation first, and look how that went.

I will be amazed if we play 3 CBs against Burnley on Sat

Eze is going to run into that a lot in his career and it’s part of why I’m not convinced he’ll end up at one of the big boys, despite his talent.

He’s a floating number 10 but hardly anyone can accommodate those anymore - even Vieira struggled to fit him in, and it’s much easier to justify at our level given the strength of the squad.

Agree but I think we're in a better position to play it this time round, we actually have ball playing CBs (Anderson/Guehi) along with an attacking RWB. LWB and the 3rd CB slot will be the biggest areas to work on in the summer, Mitchell doesn't know what he's doing that high up the pitch.
