People are focusing on the wrong things and it's probably to be expected because of how bad we are. I've seen loads of suggestions of changes which fix nothing. Thankfully Bilic seems to see the actual issues as evidenced by the changes he made at HT, sadly it was too late and I don't think Zohore is the answer.
Quite simply, the double-pivot doesn't work: Livermore is terrible at football and Sawyers is the worst defensively of any centre mid I think I've ever seen. They need another body in there as we have no other options to replace them (Barry, Brunt and Harper don't work), hence it needs to be a 433. Krov has proven he is best as an 8, and was unjustifiably dropped when that midfield was actually working.
Striker issue is simple for me at this point, all 3 are dogs**t. Austin would have got the nod but his fitness is Sunday League level. We have a proven Championship goalscorer in Robinson who has experience of playing as a striker. He's far quicker, fitter and better technically than the other 3. That also allows us to play an extra winger, which is the position we are strongest in. Grady and Grosicki can rotate on the left for me.
Back 5 are fine, I think the best 5 are the ones currently starting and any changes just make us worse in possession for marginal gains defensively.
Livermore then becomes the only weak link technically, which you'd hope we can carry as everyone else is comfortable on the ball:
Johnstone
Furlong - Ajayi - Hegazi - Gibbs
Livermore - Sawyers - Krovinovic
Pereira - Robinson - Diangana/Grosicki
