If what you're saying is true about being starved for chances, we don't need another striker in the same mould at all, we would need a creative player who is also capable of chipping in with a fair number of goals and play as a centre forward if required, or we would just be looking at the same problem, possibly worsened by the temptation to play both up top.
Not that I believe that Cisse's disappointing season can solely be attributed to a lack of service of course. For some reason, his chance conversion rate this season is nowhere to what it was last season. Maybe he is also getting fewer chances, but when he gets one he generally snatches at it way too much.
Anyway, he has been scoring more as of late, so I hope he continues in this vein and this sorry season can quickly be forgotten about.
