You saw when we get things right we are a dangerous team…I am contracted through to the Rugby World Cup."Pivac's future is now set to be discussed at what the WRU said Sunday was a "pre-planned and regular" review, although chief executive Steve Phillips did not hide his feelings."With no disrespect to Georgia, who are a growing force in the world game, this result was extremely disappointing," he said. Phillips added: "We will now review the Autumn Nation Series campaign in its entirety and in detail, as we always do."Upon conclusion of this review we will, of course, act on the outcome as we continue to work towards, the now short-term goal of success at the 2023 Rugby World Cup and the more immediate 2023 Six Nations competition, but also sustainable longer term success."Click Here: cheap sydney roosters jersey
