British & Irish Lions centre Robbie Henshaw admits it would be "unbelievable" to wrap up the series in two games but expects South Africa to come out fighting on Saturday (Match Betting - South Africa 20/21, draw 18/1, British & Irish Lions 21/20).

The three-match series could be done and dusted by the close of play on Saturday if the British & Irish Lions (2/7 Series Winner) can follow on from their 22-17 success last weekend.

South Africa (5/2 Series Winner) looked to be in control midway through the first Test, leading 12-3 at half time, however, the Lions turned things around in the second period, thanks largely to a lack of discipline from their opponents.

A string of penalties handed Dan Biggar and Owen Farrell the opportunity to land with the boot and Warren Gatland's men edged to victory.

Saturday's second Test is expected to be another tense affair and Henshaw is under no illusions as to the task that lies ahead for The Lions.

"Everyone knows we are in such a great position at the moment and it's in our hands to go out and back it up," Henshaw said.

"It's going to be very tough but it would be unbelievable to have it wrapped up in two games.

"South Africa are going to be emotionally driven. After the last game, they were saying that when their backs are to the wall, they're a dangerous team.

"They are massively dangerous and they are going to be well up for it. We need to be ready to match their power and the fire they're going to bring.

"We are expecting them to come out of the blocks fast and to throw everything at us."

Gatland has made three changes to his starting XV, with Mako Vunipola coming in to replace Rory Sutherland in Cape Town.

Ali Price drops out with Conor Murray set to start at scrum-half and centre Chris Harris replaces Elliot Daly.

South Africa have also made three changes as Steven Kitshoff, Frans Malherbe and Jasper Wiese all getting the nod from director of rugby Rassie Erasmus.
