Arsenal, Marseille Put League Worries behind Them

Arsenal and Marseille set aside their poor league form so far this season with valuable home wins in their Champions League group matches on Wednesday.

Arsenal edged Greek side Olympiakos 2-1, while Marseille, who have just one league win all season, pulled off an impressive 3-0 victory at home to German champions Borussia Dortmund.

Marseille top group F with six points from their two matches, while Arsenal are second on four.

Elsewhere, champions Barcelona eased to a 5-0 win away at BATE Borisov while AC Milan -- who grabbed a last-gasp 2-2 draw with Barca in their opening group match -- overcame Czech debutants Viktoria Plzen 2-0 at San Siro.

Arsenal made a roaring start against Olympiakos, easing into a 2-0 lead thanks to goals by 18-year-old Alex Oxlade-Chamberlain -- the third youngest scorer for Arsenal in Champions League history -- and Andre Santos.

However, some dreadful Gunners defending allowed Olympiakos back into the match six minutes later as David Fuster made them pay.

Oxlade-Chamberlain, whose father, former England international Mark, was in the crowd, said he had revelled in playing at such a high level just months after playing in League One.

"It was a really good experience," he said.

"It's a big step up, but I want to play at the top level and I have plenty more time to play in the Champions League. It's my first time in the Champions League and I'm glad we've achieved three points."

Marseille owed their victory to Ghanaian star Andre Ayew, who scored a double, the first a fine shot from the edge of the box and the second a penalty.

Loic Remy netted in between for Didier Deschamps' side.

"To have six points after two games is good," Marseille coach Deschamps told Canal+. "In the last two seasons, we had zero points (after two games). But to qualify you need a minimum of 10.

"We've made a good start, but we're not there yet."

Barcelona had wrapped up the three points by half-time as they outclassed their Belarusian hosts.

The hosts hardly helped their cause with an own goal to make it 1-0 and their goalkeeper Alyaksandr Gutor dropping the ball onto Lionel Messi's head for their third.

The Argentine maestro added another early in the second half with a rasping drive to make it 14 goals in 10 matches this season.

Milan had made heavy weather of the first half against their Czech opponents but goals by Zlatan Ibrahimovic and Antonio Cassano in the second half gave them the breathing space they required.
