Toulouse coach Pascal Dupraz has again taken aim at Manchester City boss Pep Guardiola.
City are now five games without a win under the Catalan.
"When I am asked a question about Guardiola, I'm just saying it does not appear incredible that he has these results with such teams (Barcelona and Bayern Munich)," said Dupraz.
"Somewhere along the way, the Barca-City last week gives me reason to think otherwise.
"Without (Lionel) Messi, it may be more difficult for him to win."
