Barcelona coach Xavi Hernandez said on Saturday he will resign from his post if he felt that he cannot help his Spanish team improve.

The Catalans are close to elimination from the UEFA Champions League after a draw with Inter Milan on Wednesday and have faced criticism this week, ahead of the Clasico against rivals Real Madrid on Sunday.

"I know there's a lot of pressure, a lot of criticism, this is Barca," Xavi told a press conference.

The former player stressed that he "will not stop working and trying. The day that I'm not sure (of myself), I will leave. I will not be a problem for Barcelona, the day I see I am not a solution."

Barcelona, currently La Liga leaders, face champions Real Madrid at the Santiago Bernabeu, where they won 4-0 last season.

The Spanish coach insisted that it is too early to judge his team after the new arrivals this summer and believes they are heading in the right direction.

"It's a vital game for us, and for Madrid too, let's see who comes out of it as leaders," said Xavi, adding, "I think (our) project is under construction. The debacle in Europe is sad, but we are on a good path. We are having a splendid season in La Liga."

The 42-year-old coach considered that Barcelona "have made good signings, it's too soon to draw conclusions. We have to keep working, I don't know any other path towards success."
