We don't need massive outlays to massively improve this team - because tons of relatively young players will have six months on their contracts come January, thanks to a general trend for players to let their contracts run down that started in 2020-ish and has only intensified since. I posted a list in another thread a while back.
And clubs will prefer to get money for them to losing them for nothing, precisely *because* of Omicron and lockdowns - they'll need all the income they can get.
This is exactly the time to go out and strengthen. Romagnoli (Milan, CB), Kessie (Milan, CDM), Zakaria (Gladbach, CDM), Ginter (Gladbach, CB), Boubacar Kamara (Marseille, CDM), Brozovic (Inter, CDM), Azmoun (Zenit ST), Mazraoui (Ajax RB), and more besides.
Get three of those in in Jan, and with the rest we're getting now and time for Conte to prep the team, we'll be absolutely flying come the second half of the season. This is, in effect, a pre-season for us - an invaluable opportunity that plays into our hands, a second summer.
Get January right, and top four is very much in our hands.
Hope so.
