Johan Ackermann is backing Sebastian de Klerk to make a genuine impression in the Bok environment after the Bulls winger earned a Nations Championship call-up following a six-month absence with a foot injury. Ackermann's case rests on De Klerk's work rate, physicality, and cross-positional flexibility — he can cover both wings and outside centre — qualities the Bulls coach believes Erasmus's staff will identify quickly once they work with him. With competition on the wings fierce, Ackermann isn't overselling De Klerk's immediate Test prospects, but frames the call-up as a platform: settle in, be yourself, and let the ability do the talking. Luan Giliomee's inclusion draws less credit from Loftus — Ackermann readily points to Giliomee's junior rugby and Sharks development as the real foundation — making De Klerk's selection the more Bulls-specific story here.
