Without van Persie's goals last season, Arsenal would have finished mid-table at best.
Admittedly, they've brought in Lukas Podolski and Olivier Giroud to add more firepower to the team but they're unproven in the Premier League.
Let's face it, the last few forwards that have signed for Arsenal haven't exactly set the heather alight.
Chamakh, Eduardo and Gervinho have all had their own issues with form and injury and it's put more pressure than ever on the midfield players to pitch in with their share of goals.
If Nicklas Bendtner was as good of a player as he thinks he is then he could fill the void, but he goes missing in most of the games that he plays in.
Can Podolski and Giroud score goals?
Absolutely, but will they get the volume of goals that van Persie did last season?
The jury's out on that one, I'm afraid.
