No way Barella will not start. Gags had great game, but it still doesn't change the pecking order. The only way Gags starts is if Vidal will not be as well as we expect.
I would say Eriksen will start again in front of them. Then Lukaku Lautaro upfront. Lautaro for sure, and I doubt Lukaku will be benched for Sanchez even though he is in great form. Having him and Gags to come off the bench will be usefull.
Hakimi I think is no brainier although it's possible Conte will move him back to the bench to slowly introduce him. On the left I think Perisic will get another shot. Bastoni De Vrij for sure, on the right either Skriniar or Dambrosio.
That's how I see it.
I think so far we're playing a lot more offensive game, to outscore the opponent. It's possible it will be the same here.
