Speculation is rife over the future of current Barcelona head coach Ernesto Valverde at Camp Nou, after back-to-back LaLiga champion Barca was defeated 3-2 by Atletico Madrid in the Supercopa de Espana semi-finals last week.

Valverde's position has been in doubt since a collapse in the UEFA Champions League semi-finals against Liverpool and a defeat to Valencia in the Copa del Rey final the end of last season.

Spanish media has widely reported that Barcelona chief executive Oscar Grau and technical secretary Eric Abidal had travelled to Doha to meet with Xavi.

The purpose of the trip was said to be to offer Xavi the chance to replace Valverde in the coming days, rather than wait until the end of the season.

However, Xavi is reported to have rejected Barcelona's offer, with Spanish sports daily Marca saying he will wait until June of this year or June 2021 to take over at Camp Nou.

Al Sadd confirmed its coach oversaw training ahead of the Qatar Cup final aginst Al-Duhail on 18 January (AEDT).

Xavi acknowledged he met with Barcelona officials but refused to go into detail over the meeting because of his respect for Valverde.

"Coaching Barca is my dream, I cannot hide that, everyone knows I support them from the bottom of my heart," Xavi said.

"Yes, Abidal is my friend. I've met him many times, so I cannot say anything, just that I respect Barcelona, I respect Valverde, I respect the players, I respect my club.

"They [Barca] were here to talk to me and we discussed many things. I cannot say anything else. Sorry, but I cannot inform you too much. I met Abidal, he is my friend, that's it.

"I'm doing my job here, I'm doing my best. I was focused on the semi-final and now we play the final so I'm very happy. I'm very happy to coach Al Sadd and I am focused on my team."
