West Ham's 2-0 win over Charlton on Saturday saw them climb a point ahead of us in seventh place with a game in hand.
Christian views this as the ideal incentive to ensure the snaring of the full three points when we go head-to-head at the weekend in our final London derby of the season.
"They are in front of us but, if we beat them, we will go on top," Christian pointed out. "It is a good chance and I hope we win."
Christian well recalls our 1-0 win at Upton Park in late November, but one incident sticks out in his mind more than any other. Not so much Les Ferdinand's goal, but the rather painful assist.
"I think we had a good game over there. It was a tight game and they had chances, I think we played a good game though.
"Remember as well, Gus got really hurt in that game when he collided with the post!
"It will be a tight game this time too - London derbies are special."
Christian Ziege says the fact that West Ham have jumped us in the table will add extra spice to Saturday's encounter at the Lane.
