Real Betis vice-chairman Lorenzo Serra Ferrer has confirmed that the Spanish side want to sign Chelsea midfielder Mario Pasalic.
The 22-year-old spent last season on loan at Milan but the Italians decided not to extend his stay in the Serie A.
He is expected to leave the Blues on a permanent basis this summer with Lazio also interested in securing his services.
"He is one of the candidates," Ferrer told reporters.
"I can't deny what is obvious. Then, I can't go further on this, sorry.
"We want to bring more players in the midfield.
"You will understand that I cannot give more details about negotiations. Some are going on, close to an end, and some others are in standby.
"There will be more soon."
