**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.**\n\nThe 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.\n\nMakazole 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.\n\n“The players are very disappointed but next Saturday is a cup final. That’s how we’ve got to look at it and prepare,” head coach Gatland said.\n\n“There are a few things we’ve got to tidy up. It’s 1-1 and South Africa put a huge amount of emotion into that game. We’ve got that chance next week to hopefully take the series.
