Gerard Pique remains convinced Barcelona can recover from a slow start to challenge for trophies as Ronald Koeman received backing from within the club.

After a first LaLiga goalless draw with Cadiz in their 27th meeting, Barca have managed just two wins from their five top-flight games so far. 

Meanwhile, the Catalan club have gone without scoring in two of their past three games in all competitions, as many as in their previous 41, as they continue to suffer in the absence of Lionel Messi, who departed for Paris Saint-Germain amid financial difficulties. 

Despite the underwhelming opening to the campaign, Pique has called for unity at the club in pursuit of finding resolutions to their issues on and off the pitch. 

"The club have been riding the crest of a wave for many years," Pique told Movistar after Thursday's 0-0 draw. 

"We are going through a situation we aren't used to. These are turbulent years, with the change of president, and change of coaches. Together we have to do our best to provide peace of mind. 

"Everyone wants to win. There are many ways to deal with it. We can all complain or we can work. The players are here to work. 

"Let's not look for two sides. We are all with the president and also with the coach. We can't control the noise [around the club] and don't want to think about it." 

Indeed, the goalless draw means Barca have scored just eight goals after their first five games in the league, their worst return at this stage since 2003-04 (five). 

Frenkie de Jong's late dismissal was also Barca's second red card of the season, along with Eric Garcia against Athletic Bilbao, as many as in the whole previous campaign as Koeman's side continue to lack discipline. 

However, Pique is adamant Barca will return to the top of Spanish football. 

"I don't wear the Barcelona shirt to finish second or third," he continued. "I'm here to compete for trophies. 

"Sometimes we have to face moments like this. We feel the fans are behind us and the situation is complicated for us all. 

"I'm absolutely convinced, despite the start, that we'll be competing. The team is in good spirits and have the desire." 

Koeman's relationship issues with president Joan Laporta have been well-documented, as the former appears to be heading towards the exit door if results do not come soon. 

Barca technical secretary Ramon Planes did at least reject any suggestion that Koeman will be relieved of his duties ahead of the game against Levante on Sunday. 

"Yes, it will be with Koeman, who has our support," Planes responded to Movistar after the Cadiz game. "Football is set up like this, the coaches are in permanent examination and in a big club, even more so. 

"We are Barca, the best club in the world, we have a good squad, and the objective is to win and win, because there are no transitional seasons. We have a squad to fight for the title."
