'Moments when he won't score': Bayern play down Lewandowski catching Mueller 40-goal mark

"A lot of things would have to come together. He is playing really well and is carrying the team with his goals, but the season is long," said Kovac.

"There will be moments in the season when he won't score like he is doing now."

Lewandowski has also played down smashing Bayern legend Mueller's record of a staggering 40 goals in 34 league games in the 1971/72 season, preferring instead on equalling a more modest target on Saturday of scoring in the first eight games of a league season.

"It's great to be scoring, and I hope I can keep it up. Then we'll see," said Lewandowski on the subject of catching Mueller.

The 31-year-old Pole has hit 15 goals in 11 games in all competitions this season and has netted in each of Bayern's first seven league games.

If he scores at Augsburg, Lewandowski will equal the league record of Pierre-Emerick Aubameyang who scored in the first eight games of the 2015/16 season for Dortmund.

There is a strong chance Lewandowski will score on Saturday, having scored 18 goals in 13 games against Bayern's Bavarian neighbours, including three doubles and a hat-trick in his last five games against them.
