He cannot persist with the current tactics. If we do not have any defenders that can do what he wants them to do then it's just pointless to persevere with the same formation and ideas. You can still be solid with a back 4 and 2 holding mids and having an extra player further up the pitch giving you another option to release the ball which is sorely needed right now. Our defenders are too shit and don't have the speed of thought or ability to play make in this conte system.
Well, considering everything, I feel like we are royally fucked up. And there is no obvious solution in sight.
I mean, there would. But I have my doubts referees would let us play 5-3-3 ...

.
I mean -
IN DEFENSE -
- we
do not have defenders who could both defend AND play it out from the back. Romero seems like only one who can do both. So there will be this component missing.
- we surely
do not have central defenders available who could do it in CB duo - once more - Romero seems only one capable of doing that. I mean at some game MAYBE (but very unlikely) we could try Dier-Romero CB partnership, but I doubt it works. Davies, Lenglet and Sanzhez nor Tanganga are not just dependable enough to play with 2 CBs. So from that side our hands are so tied.
- but while we cannot play with CB duo and are forced to play trio, we
do not have fullbacks who would be able to consistently carry the ball forward and create/score goals. FFS yesterday could have been very different if Sess would have done something with all the room he had. But he did not. I will not even mention Royal.
IN MIDFIELD -
- we
do not have proper, press-resistant CM who could hold the ball AND find a pass. Have been saying this for ages but Benta and PEH are JUST NOT GOOD ENOUGH. It is always visible against decent opponent - they can steal the ball back and block shots, but they cant keep it in tight areas, they cannot beat the opposition press. So we cannot really have much control of the game if our CMs look like losing possession when they have to have ball more than 1,5 seconds. And this is 100% down to Conte and his priorities. Almost ALL of the fans were screaming for such player in summer window. But he never wanted it. He seemed happy with just technically limited workhorse-like CMs. So thats what we have - those who can chase the ball but not dominate it.
IN ATTACK -
- but while we cannot play the ball through midfield in a way that we could take a moment and then pass forward / switch wings, and no chances are created from the fullback positions, we cannot use long-ball-tactics either, cause we
do not have a striker who could win long balls and keep the ball upfield. Son never-ever wins a header and unfortunately within past 2 years, Kane cannot take ball down either anymore. If we'd have someone like Toney upfront to pair with Kane and / or Son, it would be whole different story. But it does not work.
- and as last part -
in the attack we rely on good finishing by fast players... but our fast players cannot finish chances this season. If Son does not score, he is often contributing very-very little. Against ManU we played really 3-5-1. And right now there are no alternatives either. Richie has not really clicked with other attackers and he tries too much one-touch-football and loses it. I feel that if we use Son and Richie as wingers pair, we can have threat in terms of finishing, but not that much of ball control and creativitiy. Unfortunately most creative forward in Kulusevski is out injured.
So literally all of those pieces of our trouble-puzzle impact each other.
I think best we can hope for until transfer window opens is that Kulusevski would be back ASAP and Bissouma can step up a bit OR Richie would come back and actually be able to link up with Kane properly. And NO ONE ELSE GETS INJURED... EVER.
I see us surviving with lineup of -
--Son--Kane--Kulu--
--PEH--Bissouma--
-Perisic----Doherty-
-Davies-Dier-Romero
----------Lloris---------
But then, we HAVE TO buy a CB who can defend and pass + CM/AM that has good passing and ball control + RWB.
In winter, if we want to actually do anything (TOP4 finish, getting past 1st or 2nd round of CL play-offs, getting to SF of domestic cup) without such purchases I feel we will fall short on all of these.
