Harlequins and Montpellier Hérault Rugby have never met in the Heineken Champions Cup, but they have been familiar foes in the EPCR Challenge Cup and Quins won’t need reminding how the last of those five meetings – in the 2016 final - ended. The French side stormed into a 26-9 lead before Quins scored 10 points in the last 10 minutes to add some respectability to the scoreline of their second consecutive defeat by Montpellier. The English champions are a different side now, though, and enter Sunday’s Round of 16 first leg at the GGL Stadium as Pool B runners-up, having won all four of their games. Montpellier, in contrast, finished seventh in Pool A after winning two and losing two of their matches. The match kicks off at 13:00 UK and Irish time, and will be shown live on BT Sport and beIN SPORTS. Other key facts:

This will only be Montpellier’s second match in the knockout stages of the Heineken Champions Cup. They lost their only previous one, away to ASM Clermont Auvergne by a margin of 22 points (14-36, 2012/13 quarter-final).
Montpellier have won six of their previous nine games at home against English opposition in the Heineken Champions Cup. Harlequins, meanwhile, have won on six of their previous 10 trips to France and came from behind to win against Castres earlier this season (20-18).
This will be Harlequins’ fifth match in the knockout stages of the Heineken Champions Cup. They have lost all four of their previous knockout fixtures, with their heaviest defeat in that run coming away to French opposition (10-51 v Stade Toulousain in November 1997).
Despite trailing at half-time in their last four Heineken Champions Cup matches away from home, Harlequins have gone on to win on three occasions during that run. Their last seven away games have all seen them score more points in the second half than the first.
No side have conceded more points per game than Montpellier in this season’s Heineken Champions Cup (52). They have also conceded the most tries per game in the competition (7.7), with Harlequins not in the top 10 in either category.
Harlequins have scored more points in the last 20 minutes of games than any other side in this season’s Heineken Champions Cup (46), while only Cardiff (48) have conceded more points in the final 20 minutes than Montpellier (44).
Harlequins are the only side not to have conceded a scrum penalty in this season’s Heineken Champions Cup, while Montpellier are joint third for scrum penalties conceded (9).
Montpellier boast three of the four players to have averaged 20 or more completed tackles per game in this season’s Heineken Champions Cup: Jan Serfontein (20), Paul Willemse (21) and Yacouba Camara (21).
Only Munster’s Tadgh Beirne (6) has stolen more balls at the breakdown in this season’s Heineken Champions Cup than Harlequins’ Alex Dombrandt (5). Dombrandt is also the second-top try-scorer in this year’s tournament (6).
