South Africa pray for rain in Wales to toughen them up for the 2015 World Cup Though Wales have beaten the South Africans only once in 26 matches, Meyer is expecting a tough challenge. "Wales are a strong, balanced side with a simple game plan based on getting over the gain line, and I do not say that disrespectfully," he said. They have big backs and big forwards, are good in defence and attack, and they are in form. Games between the sides are always close and we will need to be motivated. That was the message too from Wales defence coach Shaun Edwards. "If you like your rugby in a gladiatorial way, then go and buy a ticket for Saturday," he said, "It will be no place for the faint of heart. We have to muscle up against these guys. Edwards was full of praise for the visitors. "Probably the best team I have ever coached against is the South Africa team of 2009, which was probably the greatest Springboks team there has ever been," he said, "but for me this is the best South African team since then." And they will be well prepared. "These guys have been together for three months so everything is stacked in their favour," said Edwards. Wales will announce their team on Tuesday, with the two Williams," Scott and Liam, likely to replace the injured Jamie Roberts and Alex Cuthbert. Bradley Davies could line up at lock alongside Alun Wyn Jones, with Ian Evans not having trained last week and Luke Charteris short of game time with Perpignan. "I feel like I am ready to run through brick walls," said the Cardiff Blues" Davies. We trained last week and it was intense and brutal, so hopefully we can transfer that to the game on Saturday.
