Reacting to the draw conducted on Monday, Johnson remains confident of his team's chances of making it to the semifinal.
"Once again we will be playing away from home so we really have to dig deep for a solid performance against Sundowns," Johnson tells KickOff.com.
"Sundowns are always dangerous, always a difficult team to beat whether you are playing them away or at home – in League matches or in cup competitions.
"They are a very competitive team; to me they stand out as one of the most dangerous sides in the country. But you cannot expect to have easy games at this stage of the competition.
"With thorough preparations and the correct mental approach we can win and progress to the next stage.
"We will have a solid and effective game plan and if the players stick to the plan, then we will do well," adds the Dikwena coach.
While it will be a tough fixture for Dikwena, they will take heart from the fact that they have already won at Sundowns this season – Henrico Botes' goal securing them a 1-0 League victory.
In fact, they have been successful in their last two visits to Atteridgeville, having also won 2-1 in April last year in another League clash.
The Nedbank matches are scheduled to be played on the weekend of April 12-14, but Dikwena will get a dress-rehearsal for that match when they host Sundowns in their next League match after the international break on March 30.
