I'm going to be away for the majority of the upcoming season but I have stumbled across a formation that reminds me of 2004 Chelsea.
So far I have seen an abundance of team counterattack animations that nearly always lead to goals.
I've also yet to concede since using it, even with a 3* GK in for 2 matches against opponents within 10% Q.
It's a 3-2-1-3-1 but I won't give anymore details just yet.

Hopefully I will be able to log in every few days and keep my training levels up.

I'm closing in on full world class physical drills now at training level 81.
