Reports in Spain say Sevilla will make an approach for Velez Sarsfield midfielder Lucas Romero, having scouted him all season.
Marca say the Argentine would cost in the region of €7m but Los Rojiblancos face competition from Anderlecht, Fiorentina and Lazio.
The 20-year-old has however been on Sevilla’s radar the whole year and would provide cover for what could be a problem area in Unai Emery’s side.
Ivan Rakitic is expected to join Barcelona while Stephane Mbia wants a Champions League team when his loan from Queens Park Rangers expires.
Cristoforo is still recovering from injury, meanwhile, which leaves on Vicente Iborra and Dani Carrico.
Sporting director Monchi has suggested Sevilla will add to every area of the pitch, with Romero tagged as the midfield newcomer.
