Guys don't be shy, give me some advice please

Last season my good striker, he did 28 goals, 14 assist and had avg rating 8.1 he won goal, assist and highest avg rating in my league.
This season after 8 games he have 0 goals, 2 assist and avg rating 7.

Only thing i have done with my team is sell one striker that was on the bench, he played maybe 3-4 games from the start. And i have bought one DC, one AML and one ST, they are all suppose to be very good and are worth around 10 mil each.

This make no sense.
