The game will start at 13h00 (18h00 SA time) at the Olympic Stadium.
Banyana, who lost 4-1 to the Swedes at London 2012, have also been paired with hosts Brazil and China in Group E of the sporting showpiece.
Van Wyk shared her thoughts with SAFA heading into the contest with the Scandinavians.
SAFA: Janine, the time you have all been waiting for has now arrived, it’s crunch time.
Van Wyk: Yes indeed, it is crunch time. The nerves are starting to kick in – the good ones though. We have been preparing for this moment for a very long time, about eight months to be precise, and it’s finally happening. The girls are feeling it and we have been talking among ourselves that this is the time we have been working so hard for. We have been meeting these girls (Sweden team) up and down the elevator, and thinking that those are the opponents we will be facing. We also were thinking that in 2012 in London it was our opening match against them and the result was not what we expected, makes it a game that is unforgettable. When people ask me today who was the toughest opponent we have ever faced, it would be Sweden who beat us 4-1 in 2012 and we were not well prepared. This time around we are looking forward to the match and going for it as best as we can, with the team high on confidence in ourselves as a group. I think we are really capable of getting a good result if we just stick together and work on the aspects we have been working on for the past eight months. This game will give us a lot of confidence going forward if we get a good result - so we are really looking forward to as it means a lot to us, probably one of the most important matches of the tournament to get a good start for ourselves.
SAFA: Any of the Sweden players you recognise from four years ago?
Van Wyk: Yes absolutely, most if not all of them and we know what a quality team they are, but so are we. Their coach is also highly experienced, so we need to focus on ourselves and I think we can give them a good run if we play our game and give our best.
SAFA: As you say, both teams (SA and Sweden) haven’t changed much from four years ago in London, does that change things?
Van Wyk: I think so, we are now much more fitter, stronger and more experienced in our play. There are ten players in our squad who were at the London Olympics, so the experience is there and we know what to expect around us. We played some international friendly matches against the world’s best teams and we know what to expect from these teams, especially Sweden. We know what they are capable of but we can also capitalise on their weaknesses as well. We will use our strength to benefit our game and see where that takes us.
SAFA: The loss (4-1 friendly defeat last week) to New Zealand wasn’t a good end to preparations and certainly not the way to go before first game of the tournament.
Van Wyk: Well it is a wake-up call, and I am glad it happened out of competition where there were some distractions around us - from being in the Olympic Village and being overwhelmed by it all. In 2012 we were not in the village, so this is a totally new experience for us, so all those distractions got the better of us and it wasn’t a good start for us. It was an indication that we need to up our game and concentrate fully on what we are here for and what we have been working hard for, for a couple of months. We are really happy that it happened, that we got a shock of our lives - luckily it did not happen against Sweden in the opening match.
SAFA: In London you were just one of the players. On Wednesday against Sweden you will lead the team as captain. How does that make you feelA?
Van Wyk: I have been thinking about it for a long time, leading my team out on to the field in the Olympic Games for the first time. But I have been captain for quite some time now, so it is not that new in a sense but I am pretty confident in the team that I will be leading out, hopefully we can do our best and show the world what South Africa is about.
