Miguel Herrera has decided to leave Javier Hernandez out of his Mexico squad so that he can sort out his future.
Sky Sports understands that Dinamo Zagreb striker Duje Cop is attracting interest from clubs across Europe.
Marco Futacs insists he would be happy to stay at Portsmouth despite their relegation to League One.
The Hungarian striker scored five goals in 29 appearances since moving to Fratton Park last summer but could not prevent Michael Appleton's side dropping out of the Championship.
"In terms of staying here next season, we will see what happens in the future," Futacs told the club's official website.
"I have talked to the gaffer and for me, as a young player, it is important to play and get as many minutes on the pitch as possible. This club has a huge history and I would be very happy to stay."
