The two strikers have been linked with exits from Newcastle United this summer.
The transfer window is looking likely to be a busy one for the Magpies as manager Rafa Benitez moulds his squad into one he believes can secure an instant return to the Premier League.
He has already secured three new signings, with goalkeeper Matz Sels, winger Matt Ritchie and striker Dwight Gayle all moving to St James’ Park.
There has also been a departure, as Andros Townsend returned to London to join Crystal Palace after they activated his release clause.
The winger is not likely to be the only one leaving though, with several first-team stars also having been linked with exits.
There may also be departures for some of the squad players, especially up front, where Benitez currently has several options available to him.
Riviere is one that may leave after a disastrous two-year spell at the club so far has yielded just one league goal.
However, according to the Chronicle Newcastle are yet to receive an offer for him, or for fellow striker Papiss Cisse.
The situation regarding the former may change in the coming weeks though, with the same report stating that Nancy have been linked with a move for the Frenchman.
