@thfcsteff - A midfield 2 of Bergvall and Palinha (away to one of the best sides in Europe no less) gets totally overrun.
I think it very much depends on the intent. If you're playing 4-2-3-1 to press and play higher up the pitch, not so much for me. It requires the FBs to be aggressive and it also possibly requires a shift to 4-3-3 when transitioning to defence. I accept that the way Frank is going about things, this might have been the case. Of course, instead, we ended up getting battered anyway.
IMV people are getting yesterday wrong, we didn't play 532 it was 523 - Palinha + Bentancur in the middle with two AMs/WFs in front with Richarlison.
I swear I saw him say somewhere it was 5-4-1? I think you might well be right though, because Richy, Odobert and Kudus were at least 8 yards away from each other at all times. It was ridiculous.
We needed an additional CM to make up for the shortfall of creativity and give us a fighting chance in terms numbers, 2 of Sarr Bergvall Bentancur alongside Palinha, instead of a third CB would have been a better option IMV, 523 vs 4231 with our options and the result/performance doesn’t change.
We will never know the answer to this really. What I think it is safe to say is that whatever formation we'd have put out, approaching the game with that degree of callow caution would've ensured the same result. Again, I have no issue with 3 at the back if the 3-5-2 is an attacking one as opposed to becoming 'the 5'.
IF we played 3 at the back, had a midfield of Porro/Sarr/Palinha/Xavi/Udogie and Richy or Tel playing off Muani, and if that side was sent out to press and play, you'd always have players within a few yards of each other and be able to progress the ball quickly and through the middle as well as using the WBs width. When in defensive transitions, Pahlinha drops in the make a 4 if a WB gets caught out of position. For me, again, the Romero to Pahlinha to Sarr or Bergy to Xavi or Kudus through the middle links could be very productive. Muani has shown (me anyway) he can drop into half-spaces, collect and run from deep, which allows his strike partner to profit or vice-versa. Of course the caveat is that this manager (currently at any rate) won't contemplate any approach remotely like that.
I could well be a victim of idealistic thinking here, but I am continuing to find it exceptionally hard to accept the 'risks' he speaks about versus the total lack of risks we see.
