Springbok front row Vincent Koch believes it will be a "surreal moment" when South Africa's Sharks face Gloucester in Friday's European Challenge Cup final in London.

Both the Sharks, the first South African side to reach a European club rugby union final, and English Premiership strugglers Gloucester will be looking to put poor domestic seasons behind them at the Tottenham Hotspur Stadium.

The Sharks, despite a squad featuring several Springbok World Cup winners in Makazole Mapimpi, Lukhanyo Am, Eben Etzebeth, Ox Nche and Koch, are languishing in 13th place in the 16-team United Rugby Championship with one round of the regular season remaining.

But victory for either the Sharks or Gloucester in the second-tier European final would guarantee the winners a place in next season's elite Champions Cup, replacing the eighth-ranked team in their league.

"If we do win this, then, I won't say the season then looks better, but it definitely looks a little bit better, you know,"? said Koch.

"It doesn't reflect what we did in the first half of the season, but how we fixed it and how we finished the season, so for us, it's very important," added the 34-year-old prop, twice a Champions Cup winner with Saracens.

"Playing in Europe is amazing. I've been there with Saracens, but there for a South African club, it's a surreal moment."

Koch, asked to pinpoint the gap between the Sharks' URC and Challenge Cup form, refused to blame the effects of long-distance flights in what are primarily two Europe-based competitions.

But the dual World Cup-winner said the team had suffered from their test stars being unavailable in pre-season ahead of South Africa's ultimately triumphant title defence in France.

"The Springboks joining a bit later, we didn't really know what the culture was until we joined, then we knew exactly what coach (John) Plumtree wanted us to do and how he wants us to play."

'MASSIVE'

Just as South Africa won all their last three games of the World Cup by a point apiece, including edging arch-rivals New Zealand 12-11 in the final itself, so too did the Sharks defeat French club Clermont 32-31 in the last four of the Challenge Cup.

"The Sharks, haven't won anything internationally yet, and for us that's massive," said Koch.

"And then of course playing on an international level, it's for South Africa once again. We want to walk away and lift the trophy and say that it was again for South Africa, and for the family, and for the fans, and for everyone, and the brand as well."

Gloucester have twice won the Challenge Cup, in 2006 and 2015, with Friday's match their fifth appearance in the final.

They finished ninth in this season's 10-team Premiership, winning just five of 18 games.

Gloucester also suffered a humiliating 90-0 loss to Northampton on May 11, having reached the Challenge Cup final the week before with a 40-23 win over Italian side Benetton Treviso.

Their poor league form turned the Challenge Cup into a priority but Gloucester director of rugby George Skivington knows how hard it will be to give Jonny May a winning send-off in what is set to be the former England wing's last game before he leaves the club.

"They (the Sharks) have got a lot of high-profile players, a lot of guys who can do things out of nowhere, which goes from back-line players to Etzebeth in the second row and World Cup-winning front-rowers," said Skivington.

He added: "Like us, their league campaign hasn't gone to plan, so both teams have a lot to play for."

Hat-trick hero James Lowe accepts Leinster must raise their game if they are to end an agonising wait for a fifth European Champions Cup rugby title.

Leinster were cruising to a third successive appearance in the final when Lowe scored his – and the Irish province's – third try to put his team 20-3 up against Northampton on Saturday in front of an ecstatic crowd of over 82 000 at Dublin's Croke Park.

But the English Premiership leaders staged an impressive fightback, scoring 14 unanswered points through two converted tries from George Hendy and Tom Seabrook, to leave Leinster clinging on to a 20-17 semifinal win.

Leinster, beaten in the last two Champions Cup finals by French club La Rochelle, will now face the winners of Sunday's second semifinal between record five-time European kings Toulouse and Harlequins in this season's showpiece match at London's Tottenham Hotspur Stadium on 25 May.

"Something almost horrific happened!" Ireland wing Lowe told TNT Sports. "We were able to build a score but we know Northampton are an amazing attacking side and we gave them too many opportunities.

"I don't think we kicked well, me personally anyway, and we let their boys run riot."

'GOT ON TOP OF US'

Leinster captain Caelan Doris, who helped force a crucial turnover late on as Northampton looked to complete a remarkable comeback, said: "They're top of the Premiership for a reason.

"As much as we back our 'D' (defence), their attack probably got on top of us at times there. It was pleasing to just about do enough in the last few minutes."

Leinster will hope to have Ireland backs Hugo Keenan and Garry Ringrose fit for the final after the pair missed the Northampton match but coach Leo Cullen insisted there would be no question of resting senior players for their intervening games in the United Rugby Championship.

"We need to concentrate on the URC now for the next couple of weeks, so we'll be picking strong teams," said Cullen.

In January last year, Northampton suffered their 10th successive defeat in the Champions Cup.

Yet on Saturday the Saints, champions of Europe in 2000 and beaten in the 2011 final by Leinster, came within sight of causing a huge upset in what was effectively a home game for their opponents, based across Dublin at Donnybrook.

"We knew we had to play through them (Leinster) and in the first half we didn't look after the ball well enough and probably tried to force things that weren't really there to start off with," said Northampton and England full-back George Furbank.

"They sort of shut up shop with 20 minutes to go and gave us a lot of kicks so it was about securing that and putting our game on the field...We came close and put ourselves in a situation where we could have and potentially should have won that game."
