Third-tier Portsmouth await Arsenal in the FA Cup fifth round after Mikel Arteta's side saw off Bournemouth on the road.
Match Report
Arsenal's love affair with the FA Cup continued with a 2-1 fourth-round victory over Bournemouth on Monday.
The competition's most successful club, with 13 wins, secured a last-16 trip to 2008 winners Portsmouth courtesy of a deserved triumph at the Vitality Stadium.
Bukayo Saka opened the scoring inside five minutes to cap a fine team move involving all 10 outfield players, with Eddie Nketiah doubling the visitors' lead before the break.
But the bad news came for Arsenal when Shkodran Mustafi landed awkwardly on his ankle after a collision before being stretchered off.
Mikel Arteta's side conceded a late goal to Sam Surridge after he came off the bench for the Cherries, whose focus will switch back to the task of Premier League survival.

Willock produces a brilliant turn in midfield and before laying the ball off to Martinelli, who plays it on to Saka.

Willock, who is inside the Bournemouth penalty area, turns Gosling and jinks past Ake before poking the ball goalwards. Travers has his angles right though and he makes a crucial block at his near post.
26' GOAL! Bournemouth 0-2 Arsenal (Nketiah)
Far too easy for Arsenal! The play is spread to Saka, who plays an early cross into the penalty area.

A really tight call by VAR but Martinelli is onside and the goal stands.
38' SAVE! Martinez denies Harry Wilson's effort
