Barcelona are 14/1 to go unbeaten in La Liga after making it seven wins from seven with a 3-1 victory at Sevilla.
Hansi-Flick's side have now scored 31 goals and conceded just seven and are five points clear at the top of La Liga heading into the international break.
Brazil international Raphinha and superstar Lamine Yamal have already scored 19 times between them this season as they continue to terrify defences across the country.
Flick is currently presiding over an ultra-successful period as Blaugrana boss, overseeing back-to-back league triumphs, as well as lifting a Copa del Rey and two Supercopa de Espana titles.
Early indications are that things are bubbling up nicely at the Camp Nou again and Flick will be keen to make an impression in Europe.
Barcelona are currently the early favourites to win the UEFA Champions League after starting the league phase with a 5-1 thrashing of Feyenoord.
