The way we set up against Utd showed us all ,neutrals, fans and (huge) critics of Fabregas, just what he can do in the correct formation. Likewise Bakayoko and to a lesser degree Cahill, who was greatly improved back in his position of last season.
The balance was right. This is largely due to Kante returning and shows how crucial it is to get a back up for him. Drinkwater fit is also a big help. Now we need to work out a set up for more attacking teams, and with all players injury free, Conte can now go about that job. With Christensen now a fully fledged player, Rudiger and Zappa in pretty good form and Moses to return, we also have Kenedy and Luiz (who I think has been more injured than we knew) who can add another dimension to our set up.
This was not just a good win, it might be the start of the serious and proper use of the squad, based on the opposition.Finally, Conte has choices.
