WATCH Bayern Munich vs Olympiacos Free Online Live Stream 2015 UEFA Champions

Bayern Munich have won five European Cup/Champions League titles.

Guardiola is in the final year of his contract, with no indication yet of whether he will extend.

Lady Luck turned her back to Olympiakos and smiled at Bayern early in the second half, as what appeared like a cross from the left by Thomas Mueller ended into the Olympiakos net on the 52nd minute.

Substitute Mario Gotze then lashed into the net with a minute of normal time remaining, before Muller converted a penalty in stoppage time to take his tally for the season to eight Bayern goals and 11 overall, including those scored for Germany.

And talking about his former side’s Champions League opener, the centre-back has said that Olympicaos will be tough opponents and will be buoyed by support from their fans.

Olympiakos are making their 17th appearance in the Champions League, more than any other Greek side.

The ex-Switzerland boss recently criticised Bayern for bringing in too many foreign players since the arrival of Guardiola, but he has now stressed that he does not necessarily feel their new strategy is a bad thing.

Bayern have won all four of their opening German league matches this season, but had to come from behind to force a 2-1 win at home to Bavarian rivals Augsburg on Saturday with two late goals.

The Thrylos also have an experienced superstar in the form of Esteban Cambiasso in their ranks, who has first hand experience of winning against both Pep Guardiola and Bayern Munich in 2010 with Inter Milan.

It sure looked like a cross, but it went in for a goal anyways. Olympiacos will also have the additional responsibility to break his telepathic understanding with Thomas Muller, who has the knack of scoring in the big tournaments such as the Champions League.

Lewandowski is aware of the atmosphere that will await the Bundesliga champions at the Stadio Georgios Karaiskakis.
