Personally I thought Cisse looked almost like a complete striker when he first signed. His hold up play, first touch and ability to bring people into the game and keep things moving had me distinctly wanting the ball given to him rather than Ba (who at the time wasn't playing well and seemed to slow everything down when he got the ball). He's not shown that at all since that time though unfortunately.
The way I see him now is that if he's not scoring, he's not contributing anything. He still generally has absolutely no composure when given time to think as well, he's shown that even this season. I was actually surprised he stuck that second goal in against Chelsea.
