The Catalans were close to breaking the deadlock midway through the first-half when Ronaldinho's powerful free-kick was tipped over by Rangers keeper Allan McGregor.

McGregor came to Rangers rescue shortly after when he blocked Carles Puyol's header from Ronaldinho's cross.

The 2006 Champions League winners continued their domination but failed to break through Rangers' impressive defense as the Gers claimed a valuable point.

Barcelona share Group E summit with Rangers on 7 points each, four ahead of French champions Lyon, who defeated Stuttgart 2-0 to heap more misery on the Bundesliga holders.

Second-half goals from Fabio Santos and Karim Benzema were enough to hand Lyon their first win of the Champions League.
