Kone is out for the season with a knee injury.
Martinez told evertontv: â€œWe have still got two outstanding options in Romelu Lukaku and Nikica Jelavic. Both are players in a good moment of form and have been working really well.
â€œYou look through the squad and we have other players who can play in that position. Steven Naismith has been playing in that role for his national side and Kevin Mirallas played that role with Olympiakos. We are not short in that position."
