Panathinaikos 0 - 0 Barcelona

The result leaves Barcelona top of Group C with seven points from three games. Panathinaikos are second with four along with Udinese who drew 1-1 with Werder Bremen.

In a game that was full of running, tough tackling and end-to-end action, neither side was able to find a winner.

Samuel Eto'o came closest for Barcelona but was twice denied by Mario Galinovic and late on failed to find the net from a tight angle after rounding the Panathinaikos goalkeeper.

Panathinaikos had showed from the start they had no intention of being overawed by the visitors with a series of biting tackles that earned a yellow card for Sandor Torghelle.

Vaggelis Mantzios drew a good save from Victor Valdes in the Barcelona goal while Ronaldhino was kept quiet at the other end by an excellent defensive performance from Loukas Vintra.

The second half, which produced a deafening chorus of boos and whistles from the crowd whenever Barcelona began to string together a sequence of passes, was equally hard-fought with Eto'o causing the most problems.

Mark van Bommel was fortunate not to get a red card for a bad challenge but his yellow card rules him out of the return match in Spain on Nov. 2. Panathinaikos midfielder Anthony Seric will also miss the game after picking up another yellow.
