Shaun Pollock expects Vernon Philander and Dale Steyn to have a big impact for South Africa against England in this summer's Test series.
The former Proteas swing bowler believes that the tourists have the edge over their opponents in the bowling department and that Philander will be a big threat to the England batting lineup alongside Steyn.
Pollock said: "They are a settled unit, Steyn is the No1 bowler in the world and is now backed up by Vernon Philander, who has come in and had a huge impact on Test cricket.
"Philander really complements Steyn, who has obviously been a huge success for many years now.
"They also have the support of Morne Morkel, who brings pace and bounce, and the strength in depth provided by Jacques Kallis. All that gives them the upper hand."
The Test series gets underway at The Oval on Thursday morning.
