Portsmouth boss Paul Hart admits they will need to sign a new striker in January.
With Aruna Dindane and Nigerian veteran Kanu likely to be selected for the African Nations Cup, Hart's forward resources look set to be depleted.
But while he refused to rule out bringing in players, Hart admitted January is not always the best time to do so.
He said: "If we do anything, there will be priorities. A striker might be one (priority) or maybe another position.
"Who's to say that January is a good time to buy players anyway? Historically, it's not. I'm not so sure it's the best time.
"Who's going to let their best players go in January and what do you actually end up getting?"
