That's largely what my opinion is based on, but quite a few quality strikers have been made to look bad by our defence in recent times. Really it should be based on what he does against crap defences and that hat-trick against Russia put's him in the frame - but he just doesn't float my boat.
Well, it depends on what Scolari wants him team to be. If he does add Deco, or another creative midfielder, like Van der Vaart, who can put the ball behind defenses, then, really, there arn't that many better strikers to latch onto those balls and score than David Villa. But, David Villa is absolutely awesome. And yeah, he absolutely destroys weaker defenses in La Liga. His record speaks for itself.
It'll be interesting to see what type of team Scolari puts. If Drogba leaves, then the team will mainly be dependent on the striker he gets.
