Last update on.The slow second Test was due to the amount of time required for refereeing decisionsSouth Africa v British & Irish Lions - Third Test Venue: Cape Town Stadium Date and Time: Saturday 7 August Kick-off at 17:00 BST. Live text commentary: Available on the BBC Sport app and website.Ronan O'Gara, a three-time tourist, says that the decisive third Test between the British and Irish Lions in South Africa has "great implications for rugby's future."The focus has been taken away from the games by the controversy surrounding refereeing that culminated in Rassie Erasmus' hour-long video.The second Test was slow and criticized by both sides. There was little flow rugby between the two teams.O'Gara said that a quality match was needed to save the series.Before their first win, the Lions vented frustration over the official South African TV match. The South Africa director of rugby Erasmus responded with an extraordinary video criticizing the refereeing of the first Test.O'Gara claims it was worse viewing than the opener, and the first 40 minutes of the second Test defeat took 62 minutes."The series is 1-1, and I don’t feel any optimism or excitement about this weekend," La Rochelle's head coach stated on Rugby Union Weekly."It is very easy to understand the anger of supporters, because there have been very few positive actions on the pitch.It is disappointing that you are comparing the best of British and Irish Lions to South Africa."There have been anger, cynicism and frustration. This series can only be saved if rugby is strong at the weekend.South Africa is too naive to be played like thatSouth Africa's physical strength helped them win the World Cup 2019Warren Gatland, Lions head coach, has hired six new players to his starting XV after the 27-9 loss last weekend.As a group of Gatland’s older Lions leave the 23, hooker Ken Owens and prop Wyn Jones join the fray.Owen Farrell, Anthony Watson, and Taulupe Faletau - O'Gara claims could have been "key" to the series - were all dropped in the final.After recovering from an Achilles injury, Finn Russell, fly-half, is back on the bench. Number eight Sam Simmonds will be his replacement in attack as he prepares to make his Lions Test debut.The world champions will be without Pieter-Steph du Toit and Faf de Klerk, with Cobus Reinach beginning at nine and Franco Mostert moving to the back row.Lood De Jager starts at lock, while 37-year-old Morne Steyn, the fly-half who won the 2009 series with a long range penalty, is on the bench.After a second Test that was dominated by physical battles at the front and heavy reliance upon kicking, South Africa had to defend their style.O'Gara said that the Lions attempted and failed to match Springboks in both areas. He also suggested that more of the same could be coming from Gatland's team.He explained that "South Africa is building.""They will invariably be better, whereas suddenly the Lions is almost an a split personality – what are we doing?"Do we now need to change our philosophy or our style? Do we want to exploit the space that is always there?""Or should we increase the number of plays we have seen? That is what Gatland did in his selection, I believe."Finn Russell aside. It indicates to me that Finn Russell thinks he's capable of getting over the line by playing that way. I don't believe it's the best way to get a win, but maybe it was in the last Test."When you try to play like they [South Africa] do, and you don’t get results it ends up pretty ugly."If there aren't more attempts, "Top level has an issue"O'Gara said players "become possessed” when they don a Lions jersey. If the current crop can perform like those that led to South Africa's 1997 series win, the tour could still be a success.The Lions only scored one try in the two Tests. Luke Cowan-Dickie crossed in a maul to lead them to a 22-17 win in the opener.There have been four attempts in the series thus far. O'Gara said that if there's not more excitement in Test 4, the game is "in danger" of losing new fans.He said, "We're seeing the Lions scoring just one try from a drive in Test rugby which indicates that there is a problem with the game at the highest level."Former Ireland fly-half, the former Ireland fly half, said that the Lions needed a "spark" to be able to win a series.He continued, "From an attacking perspective, they aren't knocking on the doors.""There is a kick-police in place, but you must have multiple threats at this level if your goal is to cause trouble."You can't win big without scoring tries."Line-upsBritish and Irish Lions: Williams, Adams, Henshaws, Aki, Van de Merwe; Biggars, Price; Jones Owens Furlong, Itoje; A Wyn Jones (c), Lawes Curry, ConanReplacements: Cowan-Dickie, Vunipola, Sinckler, Beard, Simmonds, Murray, Russell, Daly.South Africa: Le Roux; Kolbe, Am, De Allende, Mapimpi; Pollard, Reinach; Kitshoff, Mbonambi, Malherbe, Etzebeth, De Jager, Kolisi (c), Mostert, Wiese.Replacements: Marx, Nyakane, Koch, Van Staden, Smith, Jantjies, Steyn, Willemse.
