Southampton striker Guido Carrillo is on the hunt for a new club.
There is interest in the attacker from Leganes, where he played on loan last season.
But their boss Mauricio Pellegrino has spoken about the challenges involved in concluding a deal for Carrillo with Southampton.
Leganes want another loan, while the Saints want him gone permanently.
Speaking to Spanish outlet Mundo Deportivo about the transfer, Pellegrino said: "The possibilities of bringing Guido Carrillo remain difficult at this time.
"The economic possibilities make the operation very difficult."
