in my lil test Switch to target man has no impact aswell buy the way i found that striker scoring rate could be very random... for example in my first season lukaku scored 16 goals, but in next season almost with the same squad he banged almost double 29! and that without taking penalties... so lots of randomnes in the ME.
Is that league goals only? I'd be quite happy if my striker was giving me those sort of returns! He's had more goals disallowed through VAR than he has goals currently.
I'm switching it back to the original setting and leaving it as is unless I see something to change my mind
