Cape Town - Mayambela, who has a history of ill-discipline at former clubs, earned a lucrative move to the Tshwane-based outfit after some scintillating displays with Chippa United but last week it was reported in local media that the former Djurgardens winger would be released just four months into his three year deal.
"Mark has been disciplined because we were not happy with his attitude towards his job both on and off the field," the former Kazier Chiefs boss told The Sowetan.
Baxter failed to shed light on the 28-year old's misdemeanors but made it clear that players at the club have certain standards they need to fulfil to represent the club.
"We want to set standards. I have spoken to Mark two or three times. That's the situation and the club stepped in over one incident that was way off the mark. You'd better talk to the club about it," he added.
"Mark has a contract with us and I think we have obligations in that contract. He's been disciplined and whether he trains or not, that's up to the club and Mark to come to an agreement," Baxter concluded.
