Barcelona extended their winning run by recovering from an early setback to beat Sevilla 3-1 away in the seventh round of La Liga on Saturday.
Flick has described choosing his Barcelona side as “very difficult”, with the club maintaining their position at the top of the league table following another victory.
Sevilla took the lead in the 19th minute, putting the home side in front and forcing Barcelona to respond. The Catalan club then turned the match around, with a hat-trick from Raphinha Dias proving decisive.
The result means Barcelona will remain top of La Liga at least until next month. Their next fixture is at home against Getafe on 10 October.
