3-4-3 suits Johnson, Munoz, Pino and Sarr. Not sure any of them could work in a 4-4-2.
3-4-3 doesn't really suit Mitchell and Strand-Larsen might be better suited to a front two
I agree in principle. But there is flex in formations.
I would say that with Glasners 3-4-3 there is a very specific tactical requirement. The width comes entirely from the wingbacks, and not the wide forwards.
Its why we dont see Sarr/Pino running the channels, and giving an easy option down the wing for Munoz/Mitchel. (How often do we see Munoz with the ball on the half way line, with tonnes of space ahead, but Sarr isn't making the diagonal run into the channel)
Sarr has clearly thrived in this position. For many of the others its not been completely natural. Likely because instead of them getting the ball into space 1-on-1 with a full back, they are receiving the ball much more infield where space is limited.
It would require some tactical tweaks, but there is no reason that the wide forwards couldn't play a little more wide.
Tactics vs formation is the same reason our midfield dont score. Kamada in particular has scored everywhere he's played except Palace. (notice after the Shaktar game, JP was jumping on him saying that he finally scored, Kamada's response, was something like 'i dont get any chances' )
Its probably alos the reason that someone like Uche, (and Esse before) has had so little minutes. They might have bags of creativity, but thats not what Glasner is looking for. System comes first.
It can be frustrating to watch at time, and I'm 99% sure it hamstrings some players, but it also allows us to be greater than the sum of our parts.
