Filippo Inzaghi is looking for options as Mario Balotelli's transfer to Liverpool moves closer, but the Portuguese side have ruled out allowing the Colombia international to leave
Porto have insisted Jackson Martinez is not for sale amid rumours that he is a target for AC Milan.
With Mario Balotelli having arrived at Melwood to undergo a medical with Liverpool, various reports have linked Colombia international Martinez with the Serie A outfit.
Balotelli is set to sign for Brendan Rodgers' side for £16 million, and Martinez is thought to be top of Milan's wishlist to replace the former Manchester City star, having scored 61 goals in 93 games since moving to Portugal from Jaguares in 2012.
But Porto president Pinto da Costa is insistent the 27-year-old will remain at Estadio do Dragao.
Gazzetta dello Sport quote Da Costa as saying: "Jackson is incredible, we will not be selling the striker."
Balotelli's impending signing at Anfield will help fill the void left by Luis Suarez's departure to Barcelona, joining Rickie Lambert, Adam Lallana and Lazar Markovic in boosting Rodgers' attacking ranks.
