Gunners in position after home win
Champions League - Group B:Arsenal put themselves in pole position to reach the Champions League knockout rounds with a 3-1 home victory in Group B over Olympiakos at the Emirates Stadium.
Goals either side of halftime from Gervinho and Lukas Podolksi set up the Gunners' second successive win in the group before Aaron Ramsey came off the bench to score the third with the final move of the game.
Gervinho gave Arsenal the lead against the run of play in the 42nd minute with a well-placed shot but Olympiakos reached halftime deservedly all square when striker Kostas Mitroglou headed an equaliser.
Arsenal, who have never lost to Greek opposition at home, started the second half in more lively fashion and Podolski fired a second goal through a group of players after 56 minutes. Ramsey secured victory when he dinked the ball over keeper Balazs Megyeri in the fourth minute of extra time.
Montpellier's Souleymane Camara scored a 90th-minute equaliser to snatch a 2-2 draw at Schalke 04.
Teenager Julian Draxler had cancelled out Montpellier's 13th-minute lead through Karim Ait-Fana with a fine goal of his own in the 26th after a pinpoint through ball from Klaas-Jan Huntelaar.
He then earned a penalty early in the second half that left the visitors with 10 men after Garry Bocaly was sent off. Dutch striker Huntelaar had no problem converting it.
However, Camara scored with a last-gasp effort to earn a draw after Schalke had missed a handful of chances.
Schalke, Champions League semi-finalists in 2011, are on four points, two behind Arsenal, with Montpellier earning their first point in the group to move ahead of the Greeks.
