Zonal-marking wrote that Advocaat prefers Kerzhakov because he's better in bringing others to the game and his role isn't really scoring goals but giving room to the midfielders. Sure wouldn't hurt if he scores from the sitters he missed in the first game.
I'm sure Blanc got scared from the Milner chance and the Lescott goal and just said to them that draw is good as they weren't even trying second half. Which is daft.
