Left-back Saka and striker Eddie Nketiah netted inside 26 minutes as Arsenal's much-changed lineup made a dominant start and fought off a late Bournemouth rally to secure a tie against third-tier Portsmouth back on the south coast.

Saka, 18, blasted the ball into the roof of the net from a tight angle before his low cross provided a tap-in for Nketiah, who was recalled this month from a loan spell at Leeds United.

Sam Surridge scored in the fourth minute of added time to set up a nervous finale for the visitors but Bournemouth could not find an equaliser and are left to focus on the battle for Premier League survival.

Arsenal boss Mikel Arteta said they had scored two fantastic goals, but then became a little bit sloppy which he didn't like.

When asked if he was looking to bring in a defender this month, he said: "We are in the market, the club is trying to facilitate us. When we have something to say we will confirm with you."

Earlier the fifth-round draw put Liverpool on a collision course with Chelsea providing the Merseysiders get past Shrewsbury Town in their fourth round replay at Anfield.

There is also the potential of a reunion for Wayne Rooney with Manchester United as the former England striker's new club Derby County will host the Red Devils if they get through their fourth-round replay against Northampton Town.

There will definitely be an all-Premier League tie as either Southampton or Tottenham Hotspur host Norwich City, while Leicester City will meet Coventry City or Birmingham City in another Midlands derby.

Defending champions Manchester City travel to Championship outfit Sheffield Wednesday, and Sheffield United will also face second-tier opposition in the form of Reading or Cardiff City.

The ties will be played in the week commencing March 3.

FA Cup fifth round draw:

Sheffield Wednesday v Manchester City, Reading/Cardiff City v Sheffield United, Chelsea v Shrewsbury Town/Liverpool, West Bromwich Albion v Newcastle United/Oxford United, Leicester City v Coventry City/Birmingham City, Northampton Town/Derby County v Manchester United, Southampton/Tottenham Hotspur v Norwich City, Portsmouth v Arsenal.
