Seventeen points from Henry Slade proved the difference as Exeter defeated Munster 32-24 to register their second narrow Champions Cup victory in as many weeks.
Having secured a 19-18 triumph at Toulon last weekend thanks to a last-minute conversion from Slade, they needed a remarkable rally on Sunday with Munster having looked in control when they led 24-13 after 65 minutes.
Dan Frost, Jack Dunne, Ross Vintcent and Slade scored the Chiefs’ tries, with Slade converting three and adding two penalties in front of more than 13,000 at Sandy Park.
Tom Ahern, Calvin Nash, Antoine Frisch and Shane Daly scored Munster’s tries, with Jack Crowley kicking two conversions. Munster took a sixth-minute lead following a frenetic opening, their forwards exerting sustained pressure before a superb 30-metre pass from scrum-half Craig Casey gave Nash a simple run-in.
