Barcelona defender Gerard Pique says the players have a choice in mind to replace the soon-to-depart Camp Nou boss Luis Enrique at the end of the season.
According to the Spanish defender, the club should promote from within as has become a regular strategy in recent years.
The father of two believes Juan Carlos Unzue would be the perfect replacement for Enrique who has already announced he will quit at the end of the season.
"Unzué has been in the club for a long time, not only now with Luis Enrique, but also with Pep, he is sure to be a good candidate," the centre back is quoted as saying by Mundo Deportivo.
"It is not my role to choose," he added.
Unzué was a goalkeeper during a lengthy playing career in that spanned three decades between 1986 and 2003.
He joined the club as goalkeeping coach when Frank Rijkaard was in charge and stayed on in Guardiola's first season in charge.
He left to take up managerial roles at Numancia and Racing Santander and later linked up with with Enrique in 2013 when he joined Celta Vigo as an assistant and followed 'Lucha' back to Camp Nou in 2014.
The Pamplona-born coach was part of the staff when Barça completed an historic second treble in 2014/15 and is now primed to step into the hot-seat himself.
