The final five key decisions facing Wayne Pivac as he ponders seismic Alun Wyn Jones call ahead of gruelling Springbok series

How does Wayne Pivac revitalise the Wales squad after the Six Nations misadventure that saw them plunge from champions to also-rans?

Some will argue his age — he’s 33 — should count against him, but advancing years also bring wisdom and experience. There isn’t much that will unfold on a rugby field that Webb hasn’t already seen. Nor is he ever
