L. Blancas points out the biggest PSG problem with a finger © AFP

Former PSG coach Laurent Blanc, along with "Lyon," defeated his former team 1-0 on Sunday.

After the unexpected victory, the French strategist pointed out the biggest problem of the Parisian club.

"The problem with the Parisian team is that when their main goal is not achieved, it seems like it's everything, in all tournaments.

When the Champions League game ends, immediately the plans for the next season begin. It is very difficult for everyone to mobilize," said the 57-year-old Frenchman.

L. Blanc coached PSG from 2013-2016, when the club's management had already been taken over by Qatari investors. Throughout this time, the club failed to achieve the main goal - to win the Champions League, and there were several embarrassing setbacks.
