Warren Gatland has told his British and Irish Lions to prepare for a “cup final” after their 27-9 defeat by South Africa in the second Test set up a series decider next Saturday. The Lions entered half-time at Cape Town Stadium 9-6 ahead through three Dan Biggar penalties but the match then turned on its head, with the world champions taking control up-front and in the air. Makazole Mapimpi and Lukhanyo Am crossed in the third quarter while the boot of Handre Pollard did the rest, setting up a winner-takes-all scenario in the climax to the tour.
