Former Springbok fly-half Joel Stransky has dismissed South Africa's chances of beating England, describing the team as "very average".
The Boks start their November tour against the Barbarians on Saturday which will be followed by Tests against England, Italy and Wales.
Stransky, the 1995 World Cup winning fly-half who's drop goal in extra time sealed the title, has been vocal in his criticism of the Springboks under coach Allister Coetzee.
"We are going to suffer defeats – that's the reality," Stransky told BBC Radio 5 live.
"I don't think this is a team that can beat England. It's a team that will struggle against Wales. It's a team that might even struggle against Italy. The likelihood is we are going to experience defeat."
South Africa suffered a record 57-15 defeat by New Zealand in Durban last month in their most recent match, described by Stransky as a "proper slap in the face".
The former fly-half said some of the team's young players must "embrace the Springbok culture a little bit better and put their bodies and hearts on the line".
"Three years ago we had a really good side," Stransky said. "Five years ago we had a great side. Now we have a very average side. They're not particularly well coached, but if you look at the 15 players who are going to take to the field, it's not a team that can win a World Cup.
"It's not a group of players who are going to put fear into the opposition and that for us is a great concern."
