Johnson believes both Orlando Pirates and Mamelodi Sundowns have enough quality to go all the way in their respective competitions.
"That's not so bad," Johnson tells KickOff.
"Except that Simba are a very well-travelled team and are a very, very big in Tanzania.
"Now that everything is open in South Africa it will make it better for Pirates because it's two legs, home and away.

"Facing Simba at home it's very difficult, I don't know how many thousands of people they will put in the stadium,
"But the last time I was there with Ahly, they had 30 000 to 40 000 people in the stadium.
"So it will be difficult in Tanzania for Pirates, but not impossible.
"At home, you pray that Pirates supporters come out and they support the team, they don't support the individual and don't go against the coaches and things like that.
"I don't know how experienced Fadlu and Mandla are in facing Simba,
"But be prepared that all of a sudden on any given morning, there will be a lot of traffic and you will be two hours late,
"Be prepared to arrive at a hotel late at night and there will be a lot of security checks at the hotel.
"So you've got to be prepared for the worst that can happen away from the field.
"You go into the game there's only one security car, there's only one escort, but CAF says you must have four escorts."
