Former New Zealand cricketer Brendon McCullum feels South Africa will have an edge going into the two-Test series against the Blackcaps beginning at the Hagley Oval in Christchurch on February 17, saying they are a "really uncompromising side".
The Proteas have flown into New Zealand on the back of defeating India 2-1 in the three-Test series and McCullum reckons they will have an edge despite the fact that they will be playing an away rubber.
"South Africa, they just played such an uncompromising style of cricket for a long period of time, and they were really galvanised under the leadership of (former skipper) Graeme Smith in particular," McCullum, who played more than a century of Tests for the Blackcaps scoring 6,453 runs, said on SENZ Mornings on Tuesday.
