Hi @ZaZ
I am trying to use your tactics
So, on 3rd version, there are 4 tactics

Blue 3.0, Solid Blue 3.0, Light Blue 3.0, Dark Blue 3.0

And you wrote that by default,  you use Blue 3.0, Solid Blue 3.0 and Light Blue 3.0

My question is, what about the Dark Blue 3.0 ?
because FM21 only allowed to train maximum 3 tactics
