Teenager Bukayo Saka scored one and set up another in a 2-1 win against Bournemouth on Monday as Arsenal to set up an FA Cup fifth-round tie with Portsmouth.
The much-changed Gunners made a dominant start at the Vitality Stadium with left-back Saka opening the scoring after only five minutes before providing the assist for striker Eddie Nketiah to make it 2-0 on 26 minutes.
Sam Sturridge netted an injury-time consolation for the hosts to set up a nervous finale for Mikel Arteta's side but the hosts could not find an equaliser and are left to focus on the battle for Premier League survival.
No club has won the FA Cup more time than Arsenal (13) and their first-half performance was eye-catching, with 22 passes leading up to Saka's fine opening goal.
"Mikel is trying to bring back the philosophy of the Arsenal way. We did that well in the first half, not so much in the second half," Saka told BT Sport.
"I'm very pleased," Arteta said of his young charges. "Always tough to come here and win, we've done it with a young team as well.
"I have a lot of faith in them. I think they are developing really well. They are willing and hungry and will only get better."
Bournemouth's last-gasp goal them some hope, Simon Francis’ low cross eluding everybody and allowing Surridge, 21, to score his first goal for the club after a loan spell at Swansea City.
"We're very disappointed. We gave it a good go in the end," said Bournemouth manager Eddie Howe.
"It was just a poor start. Tough first half hour and we struggled to deal with their movement. We weren't ourselves. But for the last 60 minutes we scrapped and almost got something in the end."
Monday's fifth round draw set Liverpool are on a collision course with Chelsea, while holders Manchester City will travel to Sheffield Wednesday.
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.
Liverpool, who have largely been fielding a second-string side in the competition, also have a replay with Shrewsbury Town at Anfield with the winners visiting Frank Lampard’s Chelsea.
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.
Holders 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.
