Champions Barcelona made it seven wins out of seven in La Liga,setting a club record start to a campaign,with a 2-0 victory at promoted Almeria on Saturday. Lionel Messi struck the opener after 21 minutes with a wonderful solo effort but was forced to leave the pitch soon after with a hamstring problem in his right thigh.
The injury comes three days before the teams Champions League match against Celtic in Glasgow.
Brazil full back Adriano added a second goal in the 56th minute to help move Barca on to 21 points. Earlier,Valencia continued to recover from their poor start to the season with a 1-0 home win over basement side Rayo Vallecano.
Brazilian striker Jonas pounced on an error in the Rayo defence to net the only goal after 37 minutes,earning Miroslav Djukics team a third consecutive victory that put them sixth with 12 points.
Dortmund 5-0,Bayern 1-0
In Germany,Borussia Dortmund steam-rollered hapless Freiburg 5-0 while Bayern Munich plodded past VfL Wolfsburg 1-0 as the two unbeaten arch-rivals remained level on points at the top of the Bundesliga on Saturday. The two wins could not have been more different,with Dortmund creating countless chances against outclassed Freiburg and Bayern struggling to get into gear against well-organised but toothless opponents.
Marco Reus and Robert Lewandowski each scored twice for Dortmund and Jakub Blaszczykowski completed the rout while win-less Freiburg had Fallou Diagne sent off before halftime.
Bayern,who only came to life after Xherdan Shaqiri came on as a second-half substitute,took the three points thanks to Thomas Muellers first league goal of the season but coach Pep Guardiola was far from satisfied.
Both teams have 19 points from seven games with Dortmund,who have scored 21 goals to Bayerns 14,ahead on goal difference.
Hamburg SV,with former Netherlands coach Bert van Marwijk making his first appearance in the hot seat,twice came from behind to draw 2-2 at Eintracht Frankfurt. Bayer Leverkusens 2-0 win over Hanover 96 kept them one point behind the leaders in third spot while Hertha Berlin came from behind to beat Mainz 05 3-1 and Hoffenheim rallied from 3-1 down to draw 3-3 with Schalke 04.
