Flick said his players now needed to stay grounded ahead of a semi-final against either City or Lyon
Bayern Munich players will let their stunning 8-2 Champions League quarter-final victory sink in for a day but if they are to win the title they still need to work hard, coach Hansi Flick warned.
Flick, who was assistant coach of Germany in their historic 7-1 demolition of host Brazil en route to the World Cup title in 2014, said his players now needed to stay grounded ahead of a semi-final against either Manchester City or Olympique Lyonnais.
Bayern have won the domestic league and Cup double and are looking to repeat their 2013 treble winning season.
Friday the Bavarians had already scored four times in the first half against the Spanish former European champion, outclassing them with dizzying pace and quick breaks that left the Barca defence standing.
