"I think Mfundo (Vilakazi) has got a very bright future ahead of him. Where he is now, he is probably proving people wrong that he should be starting at Kaizer Chiefs," Johnson told Soccer Laduma.
"And as long as he keeps his feet on the ground, and do as much as he can in reading the game properly and improve on that and get his physicality at another level, then I think he is going to be a very good player.
"That's my opinion. Why he is not a starter you have to find out from Chiefs. That's a conversation you have to ask Chiefs.
"I think he has got a lot to prove to move to Europe because when you look at what's happening in Europe at the moment, then it draws a completely different picture, you know," added the experienced coach.
"When you look at who is in Europe now and who are the top players in Europe, then to put Mfundo in with those players.
"Whether he is ready to go to Europe and play for a bit of a smaller team, that's another story."
