Real Betis are chasing Ludogorets winger Dani Abalo.
Abalo shone during the Bulgarian champions' Champions League campaign, scoring two goals against Liverpool in the group stages.
The 27-year-old's form has continued domestically with six goals and eight assists in the A Group.
Abalo comes off contract this June and Real Betis hope to bring the former Celta Vigo midfielder back to Spain this summer.
