They're two totally different players though.
Drogba is an out and out striker, Rooney is more of a foward, not a striker.
I think both players are brilliant and in the same team would walk the league. But I'd still rather have Rooney.
Penalties are goals, doesn't matter how they're scored, a goals a goal.
You sound like our old retarded chairman "McClean can only score tap ins and penalties, and they don;t count" (Not saying you are retarded btw)
Edit:
Just thought I'd share this with you all too.
Best pitch invasion ever...
