To be honest the goals he has been scoring lately, have been really flattering to DP's performances. I have witnessed a dip in his form the last two weeks or so. Take the game against Rapid for example, he hadn't touched the ball effectively once, besides the goals scored and the assist he made. You can't argue with his effectivity and his magical moments. Nor can you argue with his scoring touch, as he has developed an eye for goal it seems. Though his overall-play hasn't been impressive. I think his performances have been rather Trezeguet-like, lately.
Don't take me for a DP-hater, as I think you know better. I'm just saying that he hasn't been as good as his goals(or attempts at goal) suggest.
