Bayern Munich went top of the Bundesliga with a 6-1 demolition of Holstein Kiel on Saturday, but it means little to Vincent Kompany as they look to reclaim their dominance in the domestic league.

Bayern's stranglehold of the German top-flight was broken last season with Bayer Leverkusen winning the title in a record-breaking undefeated run, and the Bavarians are eager to restore order this season.

Bayern are on a maximum nine points with three wins, two ahead of Borussia Dortmund and RB Leipzig, after Harry Kane scored a hat-trick in their win at Kiel.

They enjoyed an explosive opening to the match, netting three times in the first 13 minutes as Kiel made a nightmare start peppered with defensive errors, en route to a fourth straight win in all competitions this season under Kompany.

"I have said that this is just three games. I know, I know, for Bayern it is always important [to be in top spot] but it is three games at the moment," Kompany told a press conference.

"Today it was good and then Tuesday must be good again and then again, and that's the way it goes again.

"If we continue as we do now, maybe at the end of the season... I don't even want to say it. We just have to keep going."

Xabi Alonso believes Bayer Leverkusen passed their challenge to bounce back from defeat with flying colours after their 4-1 victory at Hoffenheim on Saturday.

Victor Boniface scored twice and set up Martin Terrier, with Florian Wirtz adding the other after Mergim Berisha had pulled one back for the hosts.

It was an important win for last season's domestic double-winners as they recovered from their loss to RB Leipzig in the Bundesliga before the international break.

"It was an important test for us to not concede a second goal after going 2-0 up," said Alonso, whose team had taken a two-goal lead at home against Leipzig before eventually losing 3-2.

"We reacted well and this time we controlled the game better and were more stable until the end. We know we will get our chances if we are patient and that is what we have to patiently work towards."

Leverkusen's defeat by Leipzig was their first in the Bundesliga in over a year (462 days) after winning last year's title undefeated.

However, they proved a threat on Saturday, having 20 shots, getting eight of those on target, while accumulating 3.62 expected goals.

"We were ready today to show our highest level," said Alonso. "We were serious and very professional.

"Hoffenheim made it difficult for us in the 10 minutes before the break but we came back after half-time to show sufficient energy."

Leverkusen, who have six points from three games, kick off their Champions League campaign on Thursday at Feyenoord.

Harry Kane's hat-trick ensured Bayern Munich's perfect start to their Bundesliga title charge continued as they thrashed newly promoted Holstein Kiel 6-1 on Saturday.

Jamal Musiala, Kane and Nicolai Remberg's own-goal gave the visitors a commanding lead at the break, with the England captain grabbing his treble in the first minute of second-half injury time. 

Vincent Kompany's side went ahead after just 14 seconds when Musiala finished beyond Timon Weiner, with Kane doubling their advantage six minutes later following a mistake from Lewis Holtby. 

Musiala was again involved for Bayern's third, seeing his cutback turned home by Remberg before Kane put the result beyond doubt with a fine finish from the edge of the box. 

Substitute Michael Olise notched his first Bayern goal after Alphonso Davies' shot was parried into his path, with Armin Gigovic's 82nd-minute strike taking some of the gloss off an otherwise impressive display. 

But Kane was not to be denied his hat-trick after taking a tumble in the box - dusting himself down he emphatically fired home a trademark spot-kick. 

Data Debrief: HurryKane demolishes Kiel

With his goals against Kiel, Kane has now scored against all 18 clubs he has faced in the Bundesliga.

In the division's history, only Miroslav Klose has faced more different opponents and scored against all of them (28).

Kane has also now been directly involved in 50 goals in 35 Bundesliga games for Bayern since his move from Tottenham last year. 

Only Manchester City striker Erling Haaland has reached that total quicker, managing that tally in 44 games during his stint with Borussia Dortmund. 

Champions Bayer Leverkusen cruised to a 4-1 victory at Hoffenheim on Saturday thanks to a dazzling performance by Victor Boniface.

The Nigerian scored two goals and laid on an assist, ensuring Leverkusen got back to winning ways in their first game since the international break.

The visitors struck twice in the first half an hour for a 2-0 lead, with Boniface setting up Martin Terrier for a tap-in in the 17th minute before turning scorer with a clever finish.

Mergim Berisha, making his first appearances since a knee ligament tear last November, cut the deficit for Hoffenheim just before the break from close range.

Leverkusen restored their two-goal lead courtesy of a penalty, buried by Florian Wirtz in the 72nd minute, after Dennis Geiger fouled Alex Grimaldo in the box.

Boniface then single-handedly dismantled the Hoffenheim defence with a strong run down the left, powering a shot past keeper Oliver Baumann three minutes later to lift Leverkusen to fourth place on six points.

Data Debrief: Normal business resumed

It came as quite a shock before the international break when Leverkusen's 35-game unbeaten streak in the Bundesliga ended, with RB Leipzig handing them their first defeat in 462 days.

But Xabi Alonso's side quickly shook that result off, and extended their impressive unbeaten run on the road - they are now unbeaten in 19 such matches (W16 D3). It is also the first time they have won their first two away games in a Bundesliga season.

Meanwhile, Baumann made his 464th Bundesliga appearance in this match, drawing him level with Toni Schumacher and Lothar Matthaus. This was his 92nd consecutive game in the competition.

Borussia Dortmund's work rate out of possession was key as they went top of the Bundesliga by beating Heidenheim 4-2 on Friday, according to coach Nuri Sahin.

BVB moved onto seven points from their first three league games under Sahin with their victory at Signal Iduna Park, as Karim Adeyemi scored twice in between strikes from Donyell Malen and Emre Can.

Since losing 1-0 to Schalke in 2004, Dortmund have not lost any of their last 37 Bundesliga home matches played on a Friday, tying the Bundesliga record. 

Only Werder Bremen had previously remained unbeaten at home on Fridays through 37 Bundesliga matches in a row, doing so from 1984 to 1991.

"It was a deserved win and a very good start for us but then we shut the door and I told my players that Heidenheim will not give up. So we had to keep stepping on the gas," Sahin said in his post-match press conference.

"We had a few chances and we could have finished it off earlier but we dealt well with the pressure."

Dortmund, who had new signing Serhou Guirassy in the lineup for the first time following his recovery from injury, quickly took a two-goal lead in the first 17 minutes, Adeyemi teeing up Malen for the opener before getting his first of the encounter shortly after.

"We measure our players also on assists and goals but we can only defend well if the players press. Karim took the momentum from his Germany Under-21 performances with him," Sahin said.

"The first half was our best performance so far but we want to develop further."

Champions Bayer Leverkusen travel to Hoffenheim on Saturday while Bayern Munich, on six points, will look to make it three wins from three games when they take on newly-promoted Holstein Kiel.

Xabi Alonso is hopeful the short time he has had with his Bayer Leverkusen players will be sufficient to get them back to winning ways against Hoffenheim.

Leverkusen's 35-game unbeaten run in the Bundesliga ended in their last match, losing just their second game of the campaign at home to RB Leipzig after going the whole of the last league season without a defeat.

The international break has since reduced their preparation time for the trip to Hoffenheim, but Alonso remains optimistic about their chances of bouncing back.

"It was an express preparation, with an express meeting with the team, and individual discussions," Xabi Alonso told reporters on Friday.

"Friday is our last training session with the whole team. Of course, we don't have a lot of time to prepare for Saturday, but that's our normal dynamic.

"We will see if this express meeting was efficient or not."

Leverkusen needed a late goal to snatch a 3-2 win at Borussia Monchengladbach in their opener, before going down 3-2 against Leipzig, but the manager does not believe it is all doom and gloom.

"We're doing a lot of things very well, but there are a few things we need to improve to reach our best level," he said.

"There aren't too many things, but there are important things to improve. Hopefully, we have a better performance, a more complete performance.

"It's a football and a mentality issue. We have to improve tactically, with the ball, but also with our mentality and concentration to improve and be a bit better."

The coach said that all his players returned healthy from international duty, and he took the time to back his defender Jonathan Tah after the German came under criticism from an opposition manager.

After the 2-2 Nations League draw between Germany and the Netherlands on Tuesday, Dutch manager Ronald Koeman said that Tah, who was replaced at half-time, had big problems and made a lot of mistakes.

"It's his opinion. My opinion is that Jonathan is a top player for us," Alonso said.

"What he did in the international break, the international game is not my topic. And he was here yesterday, in a good mood, with a good feeling, so that's my main concern."

Karim Adeyemi scored twice and set up another goal as Borussia Dortmund earned a 4-2 victory over visitors Heidenheim on Friday.

Adeyemi first set up Donyell Malen, who drilled his low shot through Kevin Muller to give the hosts the lead in the 12th minute.

The 22-year-old then doubled their advantage six minutes later with his first goal after completing a textbook break five minutes later.

Heidenheim briefly cut the deficit with Marvin Pieringer's powerful header after 39 minutes, but Dortmund restored their two-goal cushion before the break with Adeyemi's low drive wrongfooting the goalkeeper.

The visitors set up a nervy finish after being awarded a 74th-minute penalty for a foul by Niklas Sule on Mikkel Kaufmann, with Maximilian Breunig confidently hitting the back of the net.

But Dortmund earned a spot kick themselves in stoppage time thanks to Omar Traore's handball, and Emre Can coolly slotted in to make it 4-2.

Data Debrief: Home advantage

While it looked like Dortmund may be in for a nervy ending after Heidenheim's late penalty, that was not the case, and it means they extend an impressive home record.

The Black and Yellow are unbeaten in 37 Bundesliga home games on a Friday since a 1-0 loss to Schalke in January 2004, which is a league record, level with Werder Bremen between 1984 and 1991). 

Dortmund are unbeaten so far this campaign, but Heidenheim's six-match winning run in all competitions is now at an end.

Vincent Kompany lauded the influence of Thomas Muller after the Bayern Munich forward capped his record-breaking outing with a goal against Freiburg.

Muller made his 710th appearance across all competitions for Bayern, coming off the bench to overtake the record for the most outings for the club, set by goalkeeper Sepp Maier, who retired in 1979.

The Germany veteran marked the milestone in style, scoring to seal a 2-0 victory for Bayern after Harry Kane was also on target with a penalty on Sunday.

Muller made his Bayern debut back in 2008 when Kompany appeared in his final club appearance in Germany, before the Belgian boss left Hamburg to join Manchester City.

Their careers have now met once again, with Kompany moving to the touchline, and the Bayern head coach is delighted to have reunited with Muller in a bizarre twist of fate.

"Outstanding. I witnessed his first game. I was there with Hamburg on this pitch. 710 games later, it's unbelievable," Kompany said.

"He gave 100% in 710 games, but not only in the games, but also in training. That's what makes Thomas so special.

"There are a few more games that he can still play and we are definitely pleased that he's got a few more in his locker and the fact that he can keep going like this, it's so important for us."

Muller has now found the net in a joint-record 16 successive German top-flight seasons, matching Holger Fach, Mats Hummels, Bernd Nickel, Olaf Thon and Michael Zorc.

His 150th Bundesliga goal on Sunday, sweeping home from Serge Gnabry's cross, marked the perfect end to a special day for the 34-year-old.

As for Bayern overall, Kompany said his side's performance dipped after the break, but luckily he has players like Muller he can call upon when the need arises.

"Very positive first half, and then in the second half we were just one step later than Freiburg on second balls, and we lost a little bit of the momentum," he said.

"But then I have to say that we're very fortunate to have very good players that can come on and make the difference, and Thomas Muller came on, Kingsley Coman too, and the players from the bench were very important for us to win this game.

"Positives and things to learn and we also got to celebrate a fantastic moment for Thomas Muller and that was important as well for us today."

Thomas Muller marked his record-breaking 710th Bayern Munich appearance with a goal as they beat Freiburg 2-0 at the Allianz Arena.

Harry Kane was also on target from the penalty spot for the hosts, who made it two Bundesliga wins from two under Vincent Kompany.

Bayern broke through in the 38th minute after Max Rosenfelder was penalised for handball following a VAR review.

Kane stepped up and made no mistake as he calmly sent Freiburg goalkeeper Florian Muller the wrong way from 12 yards.

Thomas Muller climbed off the bench to seal the victory 12 minutes from time, controlling Serge Gnabry's cross before firing into the roof of the net.

Freiburg had the opportunity to grab a consolation in stoppage time after Joao Palhinha handled Ritsu Doan's shot, but Lucas Holer blazed over from the penalty spot.

Data Debrief: Muller marks historic day with landmark goal

The day belonged to Muller, who surpassed Sepp Maier to become Bayern's record appearance maker outright with 710. Fittingly, he marked the occasion with his 150th Bundesliga goal.

The 34-year-old has not found the net in a joint-record 16 successive German top-flight seasons, matching Holger Fach, Mats Hummels, Bernd Nickel, Olaf Thon and Michael Zorc.

Earlier on, Kane maintained his perfect record from the penalty spot in Bundesliga with six consecutive successful kicks.

The England captain has scored against all 17 opponents he has faced in Bundesliga, with only Miroslav Klose facing more opponents and netting against all of them (28).

Borussia Dortmund coach Nuri Sahin demanded improvements after watching his side play out a goalless draw with Werder Bremen in the Bundesliga on Saturday. 

BVB produced a meek attacking performance at the Weserstadion, with a 20-yard effort from substitute Karim Adeyemi representing their best sight of goal in the second half.

They attempted nine shots totalling just 0.63 expected goals (xG) overall, managing just 14 touches in the area to their hosts' 22.

To make matters worse, Dortmund saw centre-back Nico Schlotterbeck sent off for a second bookable offence in the 73rd minute and had to dig in for their point, leaving Sahin frustrated.

"As Borussia Dortmund, we have to perform differently, even if the team has undergone changes and has a new coach," Sahin told reporters. 

"It would be a very cheap excuse to say it is because of the transfer window. We have worked very well in the market. Still, we are expected to play better."

Dortmund have four points from their first two games of the Bundesliga season and host Heidenheim next time out on September 13, before facing Club Brugge in their Champions League opener five days later.

Bayer Leverkusen suffered their first defeat in 36 Bundesliga matches, as Leipzig came from behind to stun Xabi Alonso's side 3-2 at BayArena.

Lois Openda struck twice for Marco Rose's, who recovered from 2-0 down to make it two wins from two and move to the summit of the table.

It looked like business as usual for the reigning Bundesliga champions when they scored twice in the last seven minutes of the first half through Jeremie Frimpong and Alejandro Grimaldo.

However, Leipzig replied deep into first-half stoppage time with Kevin Kampl reducing the deficit.

Openda then brought the visitors level in the 57th minute, before a stunning long-range strike completed the turnaround 10 minutes from time, condemning Leverkusen to their first league defeat in 15 months. 

Data Debrief: Leverkusen's long streak comes to a shuddering halt

Leipzig became the first side to beat Leverkusen in a Bundesliga match since Bochum achieved the feat a staggering 462 days earlier.  

The visitors have begun a Bundesliga season with two wins from two for only the second time, also doing so in 2019-20.

They are also now unbeaten in 13 league matches, their longest such streak since Rose took charge.

As for Leverkusen, their invincible streak is officially history, as is their 29-game unbeaten run on home soil.

Borussia Dortmund were held to a 0-0 draw at Werder Bremen in the Bundesliga on Saturday.

Defender Nico Schlotterbeck was sent off for Dortmund in the second half and Nuri Sahin’s side ultimately had to settle for a point.

After an underwhelming start to the match, the visitors were more aggressive following the interval, with substitute Karim Adeyemi making an instant impact with an effort from more than 20 yards out. But Bremen goalkeeper Michael Zetterer was in place to deny the forward.

Dortmund were reduced to 10 men in the 73rd minute when centre-back Schlotterbeck received a second yellow card for sliding in on Bremen forward Justin Njinmah.

BVB still pushed for a winner despite their numerical disadvantage, but a solid Bremen defence withstood late pressure to secure a point at home.

Data Debrief: Defences on top

Neither side can claim they were hugely unfortunate not to have scored, with Dortmund’s expected goals (xG) total of 0.61 only coming in marginally ahead of the hosts (0.41).

BVB did have four shots on target, although all four came from the 58th minute onwards with two of them from substitutes in Adeyemi and Donyell Malen, while Bremen only tested Gregor Kobel – who now has two straight clean sheets – on one occasion.

It was Marvin Ducksch who had the hosts’ only shot on target in his 100th Bundesliga appearance, the first six of which came as a Dortmund player.

The result means Bremen end a run of four straight home defeats to Dortmund in Bundesliga play, although they have now gone nine such matches without a victory.

Xabi Alonso is looking for a big improvement from Bayer Leverkusen against fellow Champions League side RB Leipzig in the Bundesliga on Saturday. 

After a 3-2 league win at Borussia Monchengladbach, Leverkusen edged to a narrow 1-0 victory at fourth-tier FC Carl Zeiss Jena in the first round of the DFB-Pokal on Tuesday.

Despite winning their opening two games of the season, and maintaining their impressive unbeaten streak, Alonso said his double-winning side are far from their best selves.

"We know that we can play better and have not yet reached our top level yet. We need to work on that," Alonso told reporters on Friday.

"That's why we want to carry on working. It's a process to achieve that level, but it's our aim, and we're focused on that. And I'm confident we can do it too.

"The players know exactly what they have to do. We have a good flow in our game, and we have to maintain that so that we can work both with and without the ball."

Leverkusen and Leipzig will both play Liverpool, Inter and Atletico Madrid in the revamped Champions League, with Alonso conceding that Saturday's match could be a test of his side's potential in that competition.

"The game with Leipzig is a top match at Champions League level. They are very good opponents with very strong individual and collective quality and a great coach [Marco Rose]."

"We have eight great opponents, and it will for sure be intense, and obviously I am looking forward to going back to Anfield."

Leverkusen captain Lukas Hradecky has been ruled out due to illness and will be replaced by Matej Kovar in goal, Alonso also confirmed. 

Vincent Kompany has urged Bayern Munich to stop making mistakes ahead of their Bundesliga match against Freiburg at home on Sunday.

Bayern narrowly secured a 3-2 victory against Wolfsburg last time out, courtesy of a late goal from Serge Gnabry, after conceding twice early in the second half.

"We observe everything, delve into details to find solutions and strive to create a perfect picture. We performed very well in the first half against Wolfsburg but lost momentum just after half-time," Kompany told reporters on Friday.

"Such lapses often occur due to mistakes. However, we fought back and persevered. The mentality was commendable. We need to address these issues as a team."

Freiburg claimed an impressive 3-1 win against last season's runners-up, Stuttgart, in their first match and Kompany acknowledged that Sunday would pose a different challenge.

"It's a difficult game for us but our objective at home at the Allianz Arena is always clear," Kompany said.

Despite injuries to defensive players, including Hiroki Ito and Josip Stanisic, who are out for the start of the season, Kompany was unconcerned about the overall squad situation.

"We're close to having everyone available. I don't want to exert too much pressure. We don't have many worries. I hope we’ll have everyone fit soon," he said.

Kompany said he was excited about the new-format Champions League after Bayern found out their fate in the competition in Thursday's draw, with Paris Saint-Germain and Barcelona among their adversaries.

"It feels new and exciting. I'm looking forward to it because it'll be different. You have eight opponents in very different situations. Previously, it was often clear who would advance after four games," Kompany said.

"I’m excited about the fixtures. An away game in Rotterdam is always nice; playing at home against Paris and away in Barcelona. The key is to keep the players fit, then we can relish the games."

Xabi Alonso wants Bayer Leverkusen to click through the gears after they edged out Jena in the DFB-Pokal.

Jonas Hofmann's header was enough to send holders Leverkusen into the next round with a 1-0 win on Wednesday.

Alonso's side only allowed their lower-league opponents to have six shots, but worryingly for the Bundesliga champions, those did accumulate to 1.04 expected goals (xG).

Indeed, Hamza Muqaj missed a golden opportunity for the hosts worth 0.75 xG in second-half stoppage time.

With RB Leipzig next up in the league, Alonso knows his team have to sharpen up.

"[We faced] a good opponent and it wasn't easy," said Alonso.

"We have to work on a few things, but we are in the next round and that's what counts. Now we go straight into preparing for the next league game."

Leverkusen did bolster their defensive options, though with the signing of Nordi Mukiele.

The versatile defender has joined on loan from Paris Saint-Germain, and could be in line to make his debut against his former club Leipzig on Saturday.

Odilon Kossounou, meanwhile, has left Leverkusen to sign for Atalanta, who beat Alonso's team in last season's Europa League final, on loan.
