ESPN have different stats for Müller.
Where is Stats (Alen) when you need him?
Nick's stats were correct, but he only gave you the Bundesliga stats.
Muller played all 34 matches, started 29 of them, scored 13 and assisted 6 goals there.
Overall for Bayern last season he scored 19 goals and assisted 10 more. That was in 52 matches.
29 goals scored or assisted on 52 matches is AMAZING for someone who played his first professional season, no matter how you put it.
Add his stats for Germany (5 goals and 3 assists on 6 matches) and you see that in 2009/2010 Muller has this record:
Matches: 58 (52 as a starter)
Goals: 24
Assists: 13
