The Catalans boss admits he’s ‘disappointed’ after his side’s recent setback in the Champions League.
Xavi Hernandez has insisted he would leave Barcelona if he feels unable to improve his team.
Barcelona are on the verge of Europa League relegation after Inter held them to a 3-3 draw on Wednesday.
The Catalans are preparing to meet Real Madrid in their next La Liga game, with Xavi insisting he still feels positive about his side’s ability to bounce back.
“I understand the doubts, I know where I am. We couldn’t afford to slip up in midweek, and we did,” Xavi said in a press conference on Saturday.
“I understand how the Barca fans feel. I’m also disappointed and sad. I came here to turn the team around and we can manage that.
“If I ever feel I’m not capable of doing that, I’ll sit down here and I’ll say so.
“That’s the way I am, I’m a natural optimist. We’ve improved since last season. In LaLiga we’re going well, we haven’t lost a game yet.
“The season we’re having makes me believe I have reason to remain optimistic.
“I will not stop working and insisting on what I do. The day I don’t see it clearly, I’m going home. The day I don’t think I’m a solution, I’ll leave. It won’t be a problem. But now I’m fine.”
Barcelona are level on points with Real Madrid after eight matchdays in La Liga. A victory on Sunday could see Xavi’s side leapfrog their arch-rivals from the league’s top spot.
