Julian Nagelsmann expressed his satisfaction with Bayern Munich as the Bavarians head into the mid-season Bundesliga break top of the table.

Bayern cruised to a 4-0 victory on Friday over Wolfsburg, with Thomas Muller – who was making his 400th league appearance for the reigning champions – scoring the first and assisting Dayot Upamecano's second.

Leroy Sane soon added a curling third before Robert Lewandowski sealed victory as the Poland striker netted his 43rd top-flight goal of 2021, surpassing Gerd Muller's long-standing calendar-year record for Bundesliga goals, set in 1972 (42).

Bayern boast a nine-point lead over second-placed Borussia Dortmund, who play their game in hand against Hertha Berlin on Saturday, and former RB Leipzig head coach Nagelsmann has been pleased with his side's efforts to date.

In the three points-for-a-win era, Bayern have won the title in 14 of the 15 seasons they have topped the league at the halfway point.

"I'm very satisfied with our first half of the season," Nagelsmann told reporters. "It's not simple to score this many goals against such a compact defence. 

"We had very good control and pressed even better in the second half. The key was counter-pressing: we won the ball high and closed all gaps.

"I'm very happy with the performance. We played a lot of games recently; the first half was more difficult. The initial phase was good, then we slowed down a bit. Then [Wout] Weghorst had a chance, we were lucky, or we had a good goalkeeper, maybe a mixture of both.

"The way we played in the second half was great. The goals were outstanding."

On Lewandowski's landmark strike, Nagelsmann added: "I was very happy that he scored. It was a wonderful goal – Lewy played a great game."

Nagelsmann also reserved praise for Upamecano, who made a staggering 103 passes in Wolfsburg's half – a game-leading figure – while also leading Bayern for tackles made (five) and possession won (14 times).

"He scored a goal, which is great," the Bayern head coach continued. "We know how important it is to have goalscoring defenders when the opponent sits very deep. 

"He was very focused today. Overall, he's having a good season, except for a couple of games. We shouldn't forget he's young, he isn't 28."
