Every game requires concentration and after three weeks of fairly mediocre performances culminated by their near escape against Arsenal in the Champions League, Bayern München need to get back to aesthetically pleasing victories. Winning games is no longer enough. At least, that is the expectation for a number of people.

This weekend's focus is their game against their domestic nemesis, Bayer Leverkusen, the only side to beat them in the Bundesliga this season. However, win or lose, at 7pm on Sunday the Allianz Arena will take on a more ambient colour. In dedication to St. Patrick's Day and in acknowledgement of the warm culture that is associated with the Irish people, the Allianz will glow a strong green for two hours on Sunday evening. The Allianz Arena joins a number of other buildings that have agreed to be illuminated in green with the likes of the Pyramids of Giza, the Leaning Tower of Pisa and the London Eye also involved.

There has been a great deal of thought put into the project, one directed by Tourism Ireland. The two-hour limit on the green projection minimises the energy consumption and to avoid excessive cost and impracticability, the green light across the stadium will actually be projected using 12 LED floodlights. They've thought of everything you know?

The green is certainly fitting for Bayern's success on the pitch this season. An incredible Bundesliga season has seen them lose only one, draw three and win an incredible 21 of their 25 games so far. In the German Cup, they find themselves one game away from the final and the Champions League quarterfinal has seen them pitted against Juventus in what proves to be a mouth-watering draw.

Their task against Leverkusen will be a tough one but with a 20-point gap over the second-placed defending champions Borussia Dortmund, second gear would arguably be a viable option for Heynckes' men. Knowing Bayern and their manager however, they won't want to just win every competition they are in. This is Heynckes' farewell and he'll want to go out with his cabinet trophy glowing brighter than the aura surrounding Pep Guardiola.
