Perth Glory coach Kenny Lowe is set to leverage his connection with Diego Castro to lure another La Liga gem to the A-League.
The unnamed player is said to be an attacking midfielder with 12 years experience in the Spanish top flight.
If the deal came off and the player was anywhere near the level of the talismanic goal machine Castro, it would be a huge boost for Glory and the league.
Castro, 34, formerly of Getafe and Sporting Gijon, arrived two seasons ago and had an instant impact winning the best player in the league in his first season (the Johnny Warren Medal) and finishing runner up to Milos Ninkovic in the season just completed.
The Spanish winger has also re-signed for a third campaign in purple, as Glory look to build on their eye-catching semi final finish from last season.
Glory's next match will be a pre-season friendly with Chilean side Audax Italiano on July 12 at nib.
