Bayern Munich Comes back from: One of the best goalkeepers in the history of the sport was forced to sit out all but three games last season due to a foot injury that even threatened to keep him on the sidelines for the World Cup in Russia.
His new coach, Niko Kovac , is known for his intense personal approach quite aside from what tactics he might employ. A ball-playing 'keeper might often invite trouble, but Neuer manages to radiate calm to his teammates.
Bayern are also facing a season full of new faces with young guns like Serge Gnabry and Leon Goretzka looking to establish themselves with the German champions.
Borussia Dortmund Comes back from: It was later discovered that the midfielder suffered a rare metabolic disorder that required him to sit out basically the entire rückrunde to seek treatment.
With both of them fully fit from the go, we can look forward to the definitive revival of a remarkable, classic Bundesliga partnership on the pitch.
Marco Reus has had the worst of luck with injuries. His recent history at club level has been equally unfortunate as various different complications have limited him to only 28 league starts out of a possible 68 over the last two seasons.
However, Reus is living proof of the old football adage that form is temporary, but class is permanent. In the 11 games he managed to play towards the end of last season, Reus scored seven vital goals to help his team secure a UEFA Champions League berth despite serious challenges from teams like Bayer Leverkusen and RB Leipzig.
Borussia Dortmund escaped with three points in Bruges on Tuesday night in the Champions League, as Christian Pulisic's stroke of luck handed his team a win over Club Brugge.
The German outfit had two-thirds of possession throughout the game but in the first half, it were the hosts who had the dangerous moments.
After 20 minutes, Marco Reus was forced to make a spectacular goal-line clearance after chaos had ensued off a set piece. Just five minutes later, Roman Burki needed to stretch his whole body to keep Arnaut Danjuma's shot from the edge of the box out of the right corner of the goal.
Lucien Favre made four changes to the starting lineup, including Mario Gotze, but the team overall lacked creative spark as there was too little movement to trouble the Belgian outfit.
In the end, it was a lucky deflection for birthday boy Pulisic, who stuck a leg out as defender Matej Mitrovic wanted to clear the ball out of his own penalty area.
The ball bounced off the substitute's leg over goalkeeper Karlo Letico into the net. Dortmund stole three points in Bruges. If they go on to qualify for the round of 16, nobody will ask about the details.
BVB did not create a single scoring chance out of open play. Julian Weigl and Axel Witsel were breathing the same air in holding midfield, Gotze was falling over his own feet, while Reus was stuck in centre-forward purgatory.
Jadon Sancho was on an unsuccessful ego-spree while Marius Wolf's feet had somehow transformed into Belgium waffles.
Favre said that he will keep the rotations going until the next international break but that will mean the club will continue to struggle as not much is clicking for them.
Players introduced after 70 minutes get no rating. GK Roman Burki, 6 -- While Reus' goal-line clearance was arguably the biggest save of the night, Burki's shot out of the right corner of the goal was quite spectacular as well.
DF Lukasz Piszczek, 6 -- Apart from two irritating passes to opponents, Piszczek used all of his experience to keep things under control. DF Abdou Diallo, 7 -- Was very alert against Brugge's centre-forward Jelle Vossen and nearly scored the opener before the half-hour mark on a set-piece.
DF Marcel Schmelzer, 6 - - Was left out in the cold by Sancho far too often and had to defend a lot by himself.
Considering that he had a difficult night, he did very well. MF Julian Weigl, 5 -- An average performance by Weigl, who played his first match of the season after overcoming an injury.
He did not look comfortable in midfield next to Witsel.
