Title contenders Borussia Dortmund crushed Augsburg 5-1 in their Bundesliga opener on Saturday, with two goals from Paco Alcacer, to lay down an emphatic marker after champions Bayern Munich slipped up in their season premiere a day earlier.
Augsburg stunned the hosts with Florian Niederlechner's goal after only 30 seconds but Dortmund quickly recovered to level with Spaniard Alcacer, Dortmund's top scorer last season, in the third minute.
They turned up the tempo in the second half, scoring three goals in a span of eight minutes with lightning quick combinations that left constantly Augsburg a step behind.
Bayern, who have won the last seven consecutive league titles, looked far from ready in their 2-2 draw at home against Hertha Berlin on Friday.
While they needed some 50 minutes to get started, Dortmund were a class better than their opponents, firing 24 shots to Augsburg's five and having more than 72% possession throughout the game.
"We were surprised by the very early lead by Augsburg," said Dortmund coach Lucien Favre, in his second season in charge.
"But we stayed calm and managed to equalise quickly. We then increased the pace after the break and that was really good.
"It is a clear and well deserved result for us. We still need to work on some things and improve each day."
Bayer Leverkusen saw promoted Paderborn come back twice from a goal down before Kevin Volland fired in the winner for a 3-2 home victory over the underdogs.
Borussia Moenchengladbach and Schalke 04 shared the points after their goalless draw.
Freiburg struck three times in the last nine minutes to beat Mainz 05 3-0 while Fortuna Duesseldorf earned a 3-1 win at Werder Bremen.
