The Poland international struck in stoppage time in the second half against Augsburg to set a new standard in the German top-flight
Hansi Flick admits he did not think it was possible for Bayern Munich striker Robert Lewandowski to break the record for most goals in a single Bundesliga season.
The Poland international netted his 41st goal of the campaign when he struck in the last match against Augsburg on Saturday.
Lewandowski left it to stoppage time of the 5-2 victory to break the record set by Gerd Muller in 1971-72, and his coach thought he was doomed to end the season level with the Bayern and Germany great.
