Johnson, who was today unveiled as the coach of Dikwena, replaced Allan Freese with the Rustenburg-based outfit lying two points above the drop zone with eight games left.
In a chat with KickOff.com, the former SuperSport United mentor says it felt good to bounce back into topflight football after an eight-month absence.
"I am very happy that I am back. I have been out of football for the past eight months but today I am back and I would like to thank the management of the club for showing me this faith," Johnson says.
"I have been down this road before so I am aware of what it at stake and the demands of the job. We have good players and there is no reason why the club should be where they are on the log," he adds.
"We are not even thinking of relegation because this is not going to happen. A club as big as Platinum Stars should be challenging for top honours every season.
"With the facilities that we have, there is no reason for us to be struggling at the bottom half of the table."
Johnson's first assignment will be a League match against Ajax Cape Town on Saturday at the Royal Bafokeng Sports Palace.
