UPDATE 2-Soccer-Bayern crush Dortmund 5-0 to open 10-point lead

(Adds Dortmund coach quote)

By Erik Kirschbaum

BERLIN, April 13 (Reuters) - Bayern Munich moved closer to winning their 21st German championship on Sunday by thrashing Borussia Dortmund 5-0 and opening up a 10-point lead over second-placed Werder Bremen.

Bayern were 4-0 up after 22 minutes, Italy striker Luca Toni scoring twice after Lukas Podolski and Ze Roberto had given them a two-goal lead inside 10 minutes. Andreas Ottl got the fifth in midway through the second half.

The two teams will meet again next Saturday in the German Cup final in Berlin.

Bayern are top with 60 points, with six matches remaining. Werder Bremen, after a 5-1 win over Schalke 04 on Saturday, have 50 points, two ahead of Schalke in third. Schalke sacked coach Mirko Slomka on Sunday after that debacle.

"This was an important step for winning the championship," said Bayern's usually cautious sporting director Uli Hoeness.

"We've got a 10-point lead with only three away matches. I don't think there's much that could happen to stop us now."

Bayern are chasing three titles. They are also in the semi-finals of the UEFA Cup.
