Dortmund won the race to sign Europe's most sought-after wonderkid, Erling Haaland. at the start of January and it already looks like a cracking piece of business as he marked his debut with a hat-trick in a 5-3 away win over Augsburg.
After starting proceedings on the bench, he completely changed the game after coming on and scored three in 20 minutes to complete Dortmund's comeback after being 3-1 down.
His first and third goals displayed a veteran know-how to perfectly play the opposition offside trap, as he scored with his left foot in off the corner and then with his right, while in between he has Thorgan Hazard to thank for an unselfish, squared pass which allowed him to score from a yard.
After the winter break, it took Bayern a little while to shake off the cobwebs and get up to speed, as it took them an hour to score against Hertha. From then on, however, the floodgates opened as they scored a further three times.
Ivan Perisic enjoyed one of his best games for the Bavarians since signing on loan from Inter, and it would be the Croatian who would play a huge part in the opener as he rose high at the backpost to nod down for Thomas Muller to smash home.
He would then earn a deserved goal himself for the fourth, as he again utilised his head to glance down an attempt which proved too hot to handle for the keeper. Along with Jean-Philippe Mateta of Mainz, he had more touches inside the opposition box than anyone else in the Bundesliga this weekend with 14.
Like Dortmund and Bayern, Leverkusen made a good start to 2020 as they won 4-1 against Paderborn. Kevin Volland set the tone for the game as he scored two within the first 15 minutes with a pair of headers.
The first was set up superbly by Moussa Diaby as he clipped a cross into the box for his team-mate, who showed excellent neck strength to loop a finish into the corner. Then, only a couple of minutes later, the centre-forward was positioned perfectly at the back post to nod home after a well worked Leverkusen set-piece. He also won the majority of his duels and 100% of his aerial duels (5/5).
Thiago was typically involved in most things creative for Bayern in midfield, as he completed 89 out of 98 passes and, alongside Dayot Upamecano and Havard Nordtveit, had the most touches of anyone in the league with 121.
He helped out defensively, too, as he made 12 ball recoveries, four interceptions, and won 12/18 duels. His performance was capped off with a superb goal - Bayern's third of the day - after he rattled a strike into the top left corner from inside the box.
Back to Leverkusen, now, and Moussa Diaby impressed as well as he recorded two assists in the win versus Paderborn. While the finish from Volland was impressive for the opener, it was Diaby's cracking run and cross from the left flank which ultimately set up the goal.
To earn his second assist of the day, he once again drove down the left wing at pace, this time using his left foot to flash a perfect, low cross along the box for Kai Havertz to finish confidently.
Even though he was involved in things in dangerous areas, he misplaced just three passes in the game, too.
HONOURABLE MENTION
Koln made it four wins on the bounce in the Bundesliga after beating Wolfsburg 3-1. Jhon Cordoba (8.9) was on target twice in the game and also won a huge 17 out of 25 duels.
ROUND TO FORGET
Bayern were hungry for goals upon returning from the winter break as they put four past Hertha. They were given a helping hand from Lukas Klunter (4.4), though, as he won zero tackles, zero aerial duels (out of 5) and just three ground duels out of 12 contested.
