Warning signs are blaring for Barcelona in the Champions League and beyond

Act like you’ve been there before.

Unfortunately, most of the Barcelona players have not gotten this far in the Champions League, and it showed.

Two important figures, however, have. Hansi Flick and Robert Lewandowski. This game lacked leadership. The message was not delivered to the team that you take nothing for granted in the Champions League. Just look at the Barcelona history books, in both directions, anything can happen.

The easiest, and probably best thing to do, is for Hansi Flick to raise his hand and take the blame, although there is plenty to go around for the players as well.
