MADRID (AFP) - Barcelona striker Samuel Eto'o admitted he was so ashamed following his side's 4-0 Spanish Cup elimination at the hands of modest Getafe on Thursday night that he wanted to crawl underground.

"If I could have opened the ground to get inside, I would have done it. I felt great shame," the 26-year-old Cameroon international told a news conference in Barcelona.

"I did not sleep this night. After the match I broke out crying out of powerlessness. It is very hard, a very hard blow to all those who love Barcelona," he added.

Getafe was trailing 5-2 from the first leg in the Nou Camp but advanced to a final clash against Sevilla with a 6-5 aggregate scoreline.

Barcelona now have only the league title to play for after previously being knocked out of Europe by Liverpool.

They lead bitter rivals Real Madrid by two points in the title race but while their form is disintegrating, their rivals' is blossoming.

But Eto'o, a three-time African Footballer of the Year, said he was confident that Barcelona would be able to defend its league title.

"The season has not finished. I have a lot of faith and confidence in my teammates. I know that we can do it," he said.
