Arsenal knocked out of FA Cup with defeat by Southampton

(CNN) Arsenal's FA Cup title defense came to an end with a 1-0 defeat by Southampton in the fourth round.

After a poor start to the season, the Gunners appeared to have turned a corner ahead of Saturday's game, having gone six matches without defeat and five without conceding.

But a first-half own goal from defender Gabriel ended that run and helped the Saints progress to the next round.

"I'm really sad to be out of the competition, congratulations to Southampton," manager Mikel Arteta, who led Arsenal to an FA Cup final victory against Chelsea last year, told BT Sport.

"Disappointed to be out and disappointed with the way we lost the game, conceding in an area where we cannot give the ball away."

Arsenal was without captain Pierre-Emerick Aubameyang, who was absent due to a "personal matter," according to Arteta, and instead called upon 21-year-old Eddie Nketiah to lead the attack.

However, it was Southampton, a place above Arsenal in the Premier League table, who showed more attacking intent early on.

The Saints got the game's only goal midway through the first half when Kyle Walker-Peters's low cross deflected off Gabriel and under the outstretched arm of Leno.

Both sides had chances to add to the scoreline in the second period -- Arsenal through Rob Holding and Nketiah and Southampton through Theo Walcott -- but the game ended 1-0.

Southampton next faces Premier League rival Wolves in the fifth round as it bids to win its first FA Cup title since 1976.

"In the first half we had more punch, more power (than Arsenal) ... the team was very disciplined today against such a strong side," manager Ralph Hasenhuttl told BT Sport.

The two sides face each other again at St Mary's in the Premier League on Tuesday.

Manchester City leave it late

In Saturday's other FA Cup games, Manchester City needed a flurry of late goals to defeat League Two's Cheltenham Town.

Cheltenham, which plays three tiers below City, took a shock lead in the second half through Alfie May and was on course to produce a stunning upset with 10 minutes remaining.

Three late goals saw Manchester City breathe a sigh of relief against Cheltenham.

However, three late goals from Phil Foden, Gabriel Jesus and Ferran Torres saved City's blushes and set up a fifth-round clash against Swansea.

There were also wins for the Premier League's three other teams in action on Saturday.

Brighton defeated Blackpool 2-1, Sheffield United beat Plymouth Argyle by the same scoreline and West Ham cruised past Doncaster 4-0.
