Gaston Ramirez's agent claims both Borussia Dortmund and Atletico Madrid are interested in the Southampton star.
The Uruguay international who joined the Premier League club in a £12million deal from Bologna last summer and netted five goals in 26 top-flight appearances.
Previously, there were speculation that Fiorentina and AC Milan were monitoring the playmaker's situation, but new potential suitors have emerged - who can offer UEFA Champions League football next term.
Pablo Betancourt (Agent) told South American radio station Radio Mana Sport: "[Gaston] is currently followed by Borussia Dortmund and Atletico Madrid. Presently, it is very difficult for him to come back to Italy."
The speculation comes as Ramirez is currently in action with Uruguay in the Confederations Cup, where they are due to face Brazil in Wednesday's semi-final.
