Napoli director Riccardo Bigon has confirmed his side's interest in Porto duo Jackson Martinez and Juan Iturbe.
The Italian club were linked with a move for Martinez last summer but now it appears that they will make a move for both players at the end of this campaign.
And speaking earlier in the week, Bigon hopes a deal can be concluded soon.
He said: "A lot was said about Jackson Martinez during the summer but with the arrival of Gonzalo Higuain, things went very well for us.
"However, I don't hide that we are interested in him as well as other FC Porto players.
"When it comes to Iturbe we just need to talk with Verona, as they have the option to buy them, we don't need to talk with FC Porto, but it's always a pleasure to talk with them, as they know how to run football at a very high level."
Martinez in particular has been linked with a number of teams across Europe and has continued to impress this season for the Portuguese side.
