When he does make an appearance, Shalulile will be setting the bar high for his nation, describing it an overwhelming achievement.

"It's a wonderful feeling because you're going to see one of the best players also, the best teams, whereby you can also see how good you are football-wise," he added.
"But we're excited and ready for that [moment], it's a massive feeling because you do not want to disappoint at that level – a lot of thousands of people are going to be there.
"I know that you're going to have butterflies but those ones will eventually go away, but we're expecting an amazing full [stadium] from day one until the last day."
