Richards, formerly a Swansea player, was booed by Cardiff supporters in their season opener at Birmingham for his apparent reluctance to ‘do the Ayattolah’ – a cult Cardiff celebration which involved tapping your head with both hands.
Cardiff even went to the lengths of releasing footage that showed Richards did do the celebration at St Andrews.
Trollope told BBC Radio Wales Sport that he does expect Richards to “respect the club’s traditions.”
“I spoke to Jazz, he is aware of the club’s traditions and obligations and it is something that happened during the game that I was not aware of,” Trollope explained.
“We have got evidence and he assures us that he did it, which I think some of the supporters saw.
“But moving forward I don’t think it will be a problem.
“He performed at a good level for us on Saturday, we were pleased with his contribution, but we don’t need these things going on around it.
“He’s aware of our expectations. He was focused on the game and he did it, that’s the main thing and it is a learning curve for him for the next games as to what he should be doing.”
Cardiff travel to Trollope’s former club Bristol Rovers tomorrow night for a clash in the first round of the EFL Cup.
