Xavi has full confidence that Gerard Pique will not let off-field matters impact his performances, as he suggested the Barcelona defender will be motivated by the criticism coming his way.

Pique has had to defend himself in recent days after it emerged he had negotiated a €24million commission when the Supercopa de Espana was moved to Saudi Arabia in 2020.

The 35-year-old's sports entertainment company Kosmos was behind the deal, and leaked audio recordings led El Confidencial to report they would benefit to the tune of €4m per tournament over the six-year agreement with Saudi Arabia.

Luis Rubiales, the president of the Royal Spanish Football Federation (RFEF), defended himself in a news conference on Wednesday, two days after Pique told a Twitch stream: "I have nothing to hide, everything we have done is legal."

Another leaked discussion between Pique and Rubiales surrounded the centre-back potentially going to the Tokyo Olympics as part of Spain's squad.

While Xavi conceded the situation is difficult, he insists he trusts Pique's intentions around the Supercopa, while claiming his former team-mate will be motivated to perform better by the controversy.

"He is outgoing and likes to be on people's lips," Xavi told a news conference ahead of Barca's LaLiga meeting with Real Sociedad.

"I am more diplomatic. I know him. If he wasn't focused, I would warn him, but it [attention] gives him fuel. It's adrenaline for him. It's like a drug, in a good sense of the word. He's focused.

"Pique's Twitch didn't bother me, it [would] bother me if he didn't give it his all or didn't follow the rules. It's Gerard and I know him. I know how to manage him and he needs it. He's doing well to compete, he needs this stimulus. 

"It's very difficult, my opinion doesn't change anything. There are two people involved. I know Rubiales well, he's a noble guy.

"I trust his honesty. He must explain himself, and [so must] Pique. I think they looked for the good of the great majority. I want to think that. If it is ethical or not? There are opinions of all kinds."

Away from Pique, Xavi has his own problems to think about. Barca have lost their last two games, suffering successive home defeats across all competitions for the first time since April 2003 after reverses in the Europa League against Eintracht Frankfurt and LaLiga against Cadiz.

The latter defeat left Barca 15 points behind leaders Real Madrid, who can move 18 points clear with a win over Osasuna before the Blaugrana's meeting with La Real the following day.

"There was no anger, but I told them things clearly," Xavi said when asked what he told his players following the loss to Cadiz. "You have to be better, the game had to be won.

"I feel bad, I like to win, but I have to face reality. I will not change what I believe. In the league we had a good run until Cadiz."

Barca did have a good run, going unbeaten in 15 LaLiga matches before that 1-0 loss at Camp Nou on Monday.

They are level with Sevilla and Atletico Madrid on 60 points, but sit just five ahead of sixth-placed La Real.

Barca, though, are unbeaten in their last 11 league meetings with the Basque team and have not lost any of their last 12 LaLiga away games.
