Gameiro struggled to hold down a regular spot at the Parc des Princes last season and following the arrival of Edinson Cavani, the 26-year-old has attracted a lot of interest this summer.
Liverpool had been linked with a swoop for Gameiro, but reports in France suggest that he is now poised to make the move to Sevilla and could be set for a medical on Wednesday.
Sevilla's attacking options have been depleted after the sale of Alvaro Negredo to Manchester City, but it looks like they will now bring in Gameiro.
"I have appreciated this player for a long time, but it is his choice to leave and that choice seems to be compatible with the club's choice," Blanc told L'Equipe.
"A new adventure should start for him in Sevilla, if his transfer will be finalised."
