Arsenal and Liverpool both opened their UEFA Champions League campaigns with victories on Wednesday night, with the Gunners grinding out a 1-0 win at Napoli and Liverpool fighting back from a goal down to beat Atletico Madrid 2-1 at Anfield.

Arsenal's narrow win in Naples

Arsenal secured a hard-earned three points at the Diego Maradona Stadium, where they were made to work for every inch despite creating a string of clear-cut chances throughout an entertaining contest.

It was captain Martin Ødegaard who finally broke the deadlock, converting 15 minutes from time to settle a tight affair. The Norwegian's composure in front of goal has been a hallmark of his recent form — Ødegaard has now scored four goals in his last five appearances across all competitions for Arsenal.

The result could easily have been more convincing for Mikel Arteta's side had they been clinical with their opportunities, but they will take the win and the confidence that comes with it ahead of a demanding European campaign.

Liverpool's comeback at Anfield

Liverpool faced an early test at Anfield when Marcos Llorente put Atletico Madrid ahead in the 17th minute, punishing the hosts with a precise finish that threatened to undermine the home crowd's confidence.

The response from Arne Slot's side was swift. Dominik Szoboszlai drew Liverpool level four minutes before the break, ensuring the teams went into the tunnel on level terms. The momentum was firmly with Liverpool at that stage.

Alexis Mac Allister then settled the contest early in the second half, firing home just five minutes after the restart to complete the comeback and hand Liverpool a vital opening victory in the UEFA Champions League.
