Munich - The 51st edition of the Bundesliga begins on Friday with the clash between Bayern Munich and Borussia Mönchengladbach. The battle for the title, the European positions, and the fight against relegation will be decided later in the season, but a good start can provide the platform upon which a successful campaign can be built.

Which teams find themselves in form and will start with a bang? Which sides will be caught flat-footed as the season gets underway? bundesliga.com's form guide offers an overview of pre-season performances. This third section deals with the teams who are currently in top form.

The quadruple-winners may have suffered their first loss of the season in the Supercup, but with the changes Guardiola (pictured) has been trying to inject into the team, as well as the fact that Neuer and Ribery were missing, the loss should hardly be seen as a body blow. The victories over Hamburg and Mönchengladbach seemed to point to the return of the formidable Bayern of last season, as well as highlighting their strength in depth. For the 5-0 cup victory over Rehden, Guardiola could even afford to rest stars such as Ribery, Thiago, Javi Martinez, and captain Philipp Lahm.

Did you know that... the incumbent German champions haven’t lost a season opener since 2002, with eight victories and three draws?

By lifting the Supercup, Dortmund laid down an early marker, particularly since their impressive victory came over perennial adversaries Bayern. Up until the surprise slip-up against Gladbach in the Telekom Cup, Dortmund had continued pre-season in the same impressive vein as their Champions League performances last season. They have also added high-quality arrivals, such as Pierre-Emerick Aubameyang, Henrikh Mkhitaryan and Sokratis Papastathopoulos. Despite Mkhitaryan’s injury, Dortmund will go into Matchday 1 on a high after a comfortable 3-0 victory over Wilhelmshaven in the Cup.

Did you know that... last season, games in which Dortmund were involved saw the most goals (123)?

Leverkusen have replaced two classy, departed youngsters (Andre Schürrle and Daniel Carvajal) with some more than capable signings. Heung Min Son and Robbie Kruse strengthen the side going forward, while Giulio Donati and Roberto Hilbert provide coach Sami Hyypiä (pictured) with strength in depth in the right-back slot. They have already impressed in pre-season with friendly victories, most recently against Vitesse Arnhem (4-0). During the 6-1 victory against Lippstadt in the DFB Cup, the Werkself went diligently about their business, and unsurprisingly, their defence was rarely called into action.

Did you know that... Bayer Leverkusen have won their last five Bundesliga games? That’s the longest run of anyone in the league, Freiburg await them on the first weekend.

It became obvious throughout pre-season that Eintracht's excellent form from last season was no fluke. Big victories against Aalen, Bursaspor and Kayserispor allowed Eintracht to showcase their burgeoning attacking power. Joselu (pictured left), Johannes Flum (pictured right), Jan Rosenthal and Stephan Schröck have all been signed with the aim of improving on the strong showing from last season. The only remaining headache for Veh is the hunt for a new striker. The second round of the DFB Cup was reached with a routine 2-0 victory against Illertissen, showcasing the existing attacking personnel.

Did you know that... Eintracht lost no key players this summer? That’s absolutely unheard of for a surprise package.
