Here are five talking points from this weekend's Bundesliga action:
* Bayern Munich, who kick off their Champions League campaign this week at Benfica, will be without Corentin Tolisso for several months after he suffered a torn cruciate ligament and meniscus and will need surgery.
The Frenchman was injured in their 3-1 win over Bayer Leverkusen on Saturday, as was defender Rafinha, who will also be sidelined for some time with an ankle ligament problem.
* Paco Alcacer's first goal for Borussia Dortmund on his Bundesliga debut pleased club bosses and fans, who are hoping they have finally found a forward who can deliver.
The on-loan striker from Barcelona set up Dortmund's second goal and scored their third after coming on as a 67th minute substitute in a 3-1 win over Eintracht Frankfurt that put them in second place.
* No fewer than 13 substitutes scored over the weekend -- a Bundesliga record. All three goals in Mainz 05's 2-1 win over Augsburg were scored by substitutes. In that game, Mainz also fielded their youngest side for a Bundesliga encounter with an average age of just over 23-1/2.
* Former Germany striker Mario Gomez scored twice in VfB Stuttgart's 3-3 draw at Freiburg in his 300th league appearance on Sunday. The goals took his all-time league tally to 165, more than any other active German player in the Bundesliga.
* Werder Bremen coach Florian Kohfeldt equalled club legend Otto Rehhagel's record of staying unbeaten in his first 14 consecutive home league games after taking over.
The 35-year-old, who took charge last year and kept Bremen up, could break that record if Werder avoid defeat to Hertha Berlin on matchday five.
