Proteas interim Test coach Malibongwe Maketa is keen to see what the Gabba surface will have in store for all-rounder Marco Jansen.The tall left-arm seamer has been an important bowling component for the Proteas since his Test debut against India at SuperSport Park last year.The Gabba, in Brisbane, is regarded as the bounciest pitch in the Southern Hemisphere, and Jansen is expected to take full advantage of it when the Proteas meet Australia in the first of three Tests on Saturday.Maketa gave every indication that Jansen, whose batting has also come on in leaps and bounds to a point where Wiaan Mulder has become surplus to requirements, will form part of Saturday's match-day XI.READ | Proteas' quest (easier said than done): Muzzle Aussie 'big two'Maketa said Australia's batting line-up will be wise to what Jansen brings to the plate, but he remains a key member of their attack.
