After reading some posts around here, It has come to my understanding that the 4-5-1V kind of lost some of its effectivness in the last few seasons.

So once he doesn´t use an AMC, I guess I will change my DMC to a MC with blue arrows, and I´ve also decided to put some blue arrows on both DC´s and red arrows on the striker. I will also change the attacking mentality to normal.

In case this won´t work I may change it to a 4-3-3, following the idea that 3 strikers seems to be working nicely this season.

We will see how it goes.

Cheers.
