Rennes thrash sorry Bordeaux as pressure rises on Petkovic
Vladimir Petkovic has struggled since taking over the Bordeaux job
Bordeaux have won just three times in 21 league games under Petkovic, who left his job as Switzerland boss after leading the country to the Euro 2020 quarter-finals.
"I take full responsibility. I wasn't able to sufficiently push the players and help them shake this fear. When you're afraid, you can't play football," said Petkovic, who sidestepped questions over his future.
"I'm a fighter, my star sign is Leo. I don't give up. It's up to me now to be able to transmit this energy to the team.
"We're in a battle for survival. We must approach matches in a more combative way, with the desire to win at all costs."
