there is a game save in this post
I found in fm-arena‘s testbase striker’s CA is much higher than AMC(acceleration and pace are higher too),I want to know if the difference is from this@Zippo

Tweak version of 4123 Extreme Diamond Undervolt XIII.I changed a AF for a F9 and removed "take fewer risks" from IWBs.I changed the passing back to shorter and removed "pass it shorter" from all players with it.
Firstly congratulations to @Steelwood  for the new top rated tactic. I've kept most of it the same but put the DM on support. I have also removed dribble more to all applicable positions.And I also changed the mentality to Attack and add the Drop Off More TI. And this tactic mostly learn from @Blau .Thank you all.(My English is not so good)
played a few games, I think take more risks is not a good PI for this tactic because my Mbappe always passes the ball to the opposing player when it is a nice chance to shoot
