Hamburg, Sep 17 (DPA) Holders Barcelona began their Champions League defence with a goalless draw at Inter Milan, while Arsenal came from two goals down to earn a victory against Standard Liege.

The barren draw between Barcelona and Italian champions Inter Wednesday night in a Group F match, left Dynamo Kiev to enjoy top spot in the group after a 3-1 victory over Russian title-holders Rubin Kazan.

Barcelona enjoyed the greater possession in San Siro and there was early chance for Sweden striker Zlatan Ibrahimovic against his old club, but neither he nor Samuel Eto'o, who moved the other way to Inter, were able to break the deadlock.

Barcelona coach Josep Guardiola told Sky pay TV: 'I am satisfied with the result. We wanted to win but the draw is OK. We tried everything but it is not easy when you are against nine men in defence.'

Inter coach Jose Mourinho was also satisfied with the point.

'Anyone who understands football will have seen that this was a game of the highest quality,' he said.

Standard Liege stunned last season's losing semi-finalists Arsenal with two goals in the opening five minutes on the Belgian side's Champions League debut in a Group H match.

Eliaquim Mangala struck home from just outside the area in the second minute and Milan Jovanovich converted a penalty three minutes later after being brought down by William Gallas.

Danish striker Nicklas Bentner put Arsenal back in the game just before the break, and two late goals in three minutes from Thomas Vermaelen and Eduardo turned the game round.

Liege protested in vain that Vermaelen's 78th-minute equaliser from right in front of goal had come after a handball from Alex Song following a Cesc Fabregas free-kick.
