Abraham scored 30 goals past 2 seasons in around 4500 mins (which equals 50 games). Plus 12 assists and penalties won. But for 99% of fans Tammy is shit.
Looking at this numbers it is fair to assume if Tammy is our number one striker every game he will give you 20-25 goals per season... But it is not enough, people want more in overall play...
So this is major concern people have with Lukaku, he will score a lot of goals but will he give us that more?
