Le Havre fan held over racist insults
"Around the 55th minute, a so-called Le Havre fan has been arrested by police because he had been shouting racist insults to John Mensah," Aulas told reporters.
"It started during the warm-up and it went on during the whole first half."
Coach Claude Puel added: "John was shocked. He heard some scandalous words."
Mensah was sent off for a second bookable offence 20 minutes from time and Puel said he should have replaced him because the player was too upset to play.
"It's my fault, I should have substituted him before," he said.
