The month following Bayern's win over Hertha Berlin to claim the title has seen their defensive numbers slip. In the 10 games played in the league, cup and Champions League since March 25, the side have shipped 14 goals. It is an average of 1.4 per game, more than three times higher than their average between the start of 2014 and then.
From January 24 to March 22, the Bavarians played 13 games and let in only five goals. They also kept six consecutive clean sheets. An average of 0.38 goals per game which can be beaten by very few sides.
Bayern's numbers at the Allianz Arena during the Champions League are neither outstanding like the start of the year, nor bad, like the past month. In the six games played they have conceded four goals (0.66 per game). The last three rivals (Manchester City, Arsenal and Manchester United) have all beaten Neuer.
Pep Guardiola warned his side about the dangers of taking their foot off the gas. They left the Bernabéu hurt last week, but on Tuesday have the chance to avenge the situation. Real Madrid, however will have other plans, and will want to carry on Bayern's bad month.
