Team news
Arne Slot named an unchanged starting XI from the win over Arsenal a fortnight ago, while Frimpong returned as a substitute after injury.
Alexander Isak was not included in the matchday squad, with Slot saying pre-match that Liverpool are aiming for the striker to be able to make his debut against Atletico Madrid on Wednesday.
Liverpool: Alisson, Van Dijk, Konate (Frimpong, 87), Kerkez (Robertson, 38), Wirtz (Ngumoha, 87), Szoboszlai, Mac Allister (Bradley, 46), Salah, Gakpo, Ekitike (Chiesa, 72), Gravenberch.
Unused subs: Mamardashvili, Gomez, Endo, Bradley, Nyoni.
First half
Liverpool monopolised possession in the early stages, though Burnley goalkeeper Martin Dubravka remained untested.
Indeed, the game’s first attempt of note was the hosts’ as Jaidon Anthony shot over the crossbar from 18 yards.
Ibrahima Konate headed over from no more than a couple of yards out amid a flurry of corners for the Reds and set-pieces felt like the likeliest avenue for success with their passing lacking fluency as the rain fell heavily.
Slot opted to bring Andy Robertson on for Milos Kerkez – who had earlier been booked – in the closing stages of the first half, and the Scot’s first action was to burst into the area before having an effort on goal saved.
Hugo Ekitike then toe-poked wide after driving in from the left and a half low on goalmouth action ended goalless.
