Olivier left South Africa some two years ago regarded as possibly the best short-bowler in the country, but has had to adapt his style.
His Instagram account goes by the name duanneolivier74.
I want to see things going forward and I feel like my cricket will improve playing county cricket.
Personally, I don't think I would have been in the World Cup squad as they have enough bowlers.
He has also picked up a further 14 white-ball wickets in as many appearances across the Royal London Cup and T20 Blast.
I think his main role should be with the new ball.
