Bayern Munich have it all to do on Tuesday when they will look to overturn a 3-1 first-leg deficit against Porto in the Champions League quarter-finals.
The five-time champions suffered a comprehensive defeat in Portugal last week as Porto took a big step towards reaching the last four of the competition.
Bayern Munich
Bayern Munich were given a bolt from the blue last week as they saw their hopes of making it through to the semi-finals dented with a chastening 3-1 defeat at the Estadio do Dragao.
However, captain Phillip Lahm insisted after the game that the Bavarians still have a great chance of progressing.
Coach Pep Guardiola commented in the wake of his side's defeat that he was unsurprised by the outcome, but added that the tie remains far from over.
Bayern's defeat in the first leg was their second in six Champions League matches. In total, they have won three of their last six games in Europe.
While their Champions League hopes hang in the balance, normal service was resumed in the Bundesliga over the weekend as they earned a 2-0 victory over Hoffenheim. With a healthy lead at the top of the table, it would take a jaw-dropping slump in form to stop Bayern from retaining their league title.
The Bayern players will be aware that they did themselves no favours during a disastrous first leg, but the tie is certainly still alive. An early goal would change the whole tone of the encounter, while the team's passionate fans are also sure to play a big part at the Allianz Arena.

Porto
Despite their rich history in the Champions League, Porto provided much of the footballing world with a shock last week when they earned a 3-1 win over Bayern at the Estadio do Dragao.
The last time that the Portuguese outfit reached the semi-finals of the tournament was back in 2004 - when they famously lifted the trophy under Jose Mourinho.
Julen Lopetegui's men have been in sensational form since the start of 2015, winning 13 of their last 16 games. More recently, they have put together four consecutive victories in all competitions.
In this season's Champions League, Porto have failed to taste defeat in all 11 of their matches so far. They have won their previous two outings on the bounce.
One the domestic front, the 27-time Primeira Liga champions currently sit in second place in the table, three points behind Benfica. They extended their unbeaten run to 11 games at the weekend thanks to a narrow 1-0 triumph over Academica.
While many will be thinking that they already have one foot in the last four, the Porto players will be well aware that they have a huge task in seeing off Bayern during the second leg. That said, they will be likely to seal their progress if they show the same kind of dominance as they did last week.

Head To Head
There is nothing to separate these teams when it comes to past meetings. Porto's victory last week was their second over Bayern, who also have two wins over Porto. They have also played out two draws down the years.
The two clubs have met twice before in the Champions League quarter-finals, with Bayern prevailing on both occasions.
We say: Bayern Munich 2-0 Porto
Despite having a 3-1 deficit to make up, Bayern's away goal could prove vital come the end of the tie. Pep Guardiola would have been seething following the first leg, so expect the Bavarians to look completely different this time around. Porto remain a threat and will undoubtedly provide stern opposition, but they could be forced to defend for their lives during the match.
