With excitement building for this weekend's European Rugby Champions Cup semi-finals, we look back at some memorable last-four ties from past seasons.

If your favourite isn’t here, don’t worry - we’ve got another set arriving shortly as we take a trip down memory lane before what promises to be an epic weekend of action.

2017 ASM Clermont Auvergne 27 Leinster Rugby 22
Clermont withstood a fine second-half fightback from Leinster in Lyon to clinch their third Champions Cup final appearance in five years.

Tries from Peceli Yato and David Strettle helped Clermont into a 15-0 lead, but four Johnny Sexton penalties reduced the deficit to three points and although Garry Ringrose scored a sensational 50m try, two drop-goals and a penalty from Heineken Man of the Match Camille Lopez helped sealed the TOP 14 side's win.

2015 RC Toulon 25 Leinster Rugby 20 (after extra-time)
Bryan Habana's extra-time interception try earned Toulon their third successive Champions Cup final appearance after they had been deadlocked with Leinster at 12-12 on 80 minutes in Marseille.

The first 89 minutes were a goal-kicking contest between Toulon's Leigh Halfpenny and Leinster's Ian Madigan, with Halfpenny landing six penalties and Madigan five, but Habana's try in only the third semi to go into extra time in 20 years ended the stalemate.

Sean O'Brien snatched a 94th-minute try for the Irish province, but Jimmy Gopperth's conversion hit the upright, the second Leinster kick to come back off a post, and Toulon were able to hang on for the victory.

2014 Saracens 46 ASM Clermont Auvergne 6
Saracens stormed into their first ever European Cup final by shattering three semi-final records in disposing of 2013 runners-up Clermont at Twickenham.

The Premiership side notched the most points by a team, most tries by a team and biggest winning margin as they ran in six tries through Chris Ashton (2), Owen Farrell, Chris Wyles, Tim Streather to add to a penalty try, with Alex Goode converting five and kicking a penalty.

2012 ASM Clermont Auvergne 15 Leinster Rugby 19
Leinster stayed on target for an historic third European Cup success in four years after edging a hard-fought tie at Bordeaux's Stade Chaban-Delmas.

Cian Healy's second-half try – the only one of the game – proved crucial in a goal-kicking battle between Clermont's Brock James and Leinster's Johnny Sexton as Wesley Fofana had a late touchdown disallowed by the TMO for losing control of the ball.

2009 Munster Rugby 6 Leinster Rugby 25
A club-match world record crowd of 82,208 saw Leinster demolish Munster at Croke Park and reach their first European Cup final.

Tries from Gordon D'Arcy, Luke Fitzgerald and Brian O'Driscoll, plus two conversions and a penalty from Johnny Sexton, and a Felipe Contepomi drop-goal, pulled Leinster clear of their Irish rivals, for whom two Ronan O'Gara penalties were their only scores.
