The South African rugby team, the Springboks, are attempting to set a world record later today when they play England at Twickenham.
If South Africa win it will be their eighteenth consecutive victory, beating the record of seventeen wins the New Zealand All Blacks achieved between 1965 and 1969.
In their run of success, the Springboks have beaten all the top sides including Australia and New Zealand.
