The Scottish region were similarly committed in their opening round encounter with Stade Rochelais when they were handed a 20-13 defeat, but were undeterred as they picked up a first win in this season’s competition against the 2020 champions.

Fly-half Ross Thompson kicked 15 points for Glasgow, with Exeter only getting on the scoreboard in the final 10 minutes through a Sam Simmonds try, but the hosts wrapped up their success when Johnny Matthews went over in the final play of the game.

Leicester Tigers also needed a battling performance to overcome Connacht Rugby in Pool B, triumphing 29-23 at Mattioli Woods Welford Road to make it back-to-back wins over the opening two rounds.

The Gallagher Premiership leaders were good value for their win, as they were against Union Bordeaux-Bègles in Round 1, but went into half time trailing after tries from Connacht’s John Porch and Jack Carty cancelled out efforts from Nic Dolly and Bryce Hegarty.

Tigers dominated the scrum over the final half an hour and Freddie Steward and Hosea Saumaki crossed to hand them a bonus point win.

Ulster Rugby also made it two wins from two as they beat Northampton Saints 27-22 in Pool B at Kingspan Stadium on Friday.

Rob Herring, Ethan McIlroy and Craig Gilroy all dotted down for Ulster in addition to a penalty try in the first half, but Alex Mitchell and Courtnall Skosan crossed for Northampton to keep the visitors in touch.

Munster Rugby were another Pool B side to maintain a 100%-win record – the Irish province recorded a 19-13 victory over Castres Olympique at Thomond Park.

Fly-half Ben Healy kicked 14 points for Munster while Jack O’Donoghue scored their solitary try, with Kevin Kornath going over late on for the TOP 14 outfit.

Harlequins top Pool B after they ran out 43-17 winners against Cardiff Rugby at Twickenham Stoop - Danny Care, Marcus Smith, Alex Dombrandt (2), Joe Marchant and Andre Esterhuizen grabbing the hosts’ tries.

An inexperienced Cardiff side threatened to pull off a shock as they crossed through Cam Winnett, James Botham and Theo Cabango.

Glasgow Warriors were one of the top performing sides across the weekend’s Heineken Champions Cup Round 2 matches, putting in a strong display as they overcame Exeter Chiefs 22-7 in Pool A at Scotstoun Stadium.
