Holders Arsenal have been sent crashing out of the FA Cup as a Gabriel Magalhaes own goal gave Southampton a deserved 1-0 win in their fourth-round tie on the south coast.
It was just the start to his new career with the Premier League giants Arsenal that Australia goalkeeper Mat Ryan, who had moved to the club on loan from Brighton 24 hours earlier, would have been desperate to avoid.
Ryan, brought in as an understudy to Bernd Leno for the rest of the season, watched from the substitutes’ bench as the German was beaten in the 24th minute when Gabriel inadvertently turned in Kyle Walker-Peters’ cross.
Arsenal boss Mikel Arteta had made seven changes to his side and was without captain Pierre-Emerick Aubameyang for personal reasons as the 14-time winners were outplayed by a strong Saints’ team.
Southampton should have won by a bigger margin but now face a trip to Wolves in round five as Gabriel’s poor return to the Arsenal side was capped by his own goal.
Saints started brightly with James Ward-Prowse hitting the crossbar direct from a corner as he looked to catch Leno off his line.
Saints took the lead when Mohamed Elneny gave away possession on the edge of his own box.
The ball was worked wide to Walker-Peters, whose cross-cum-shot was deflected into the net by Gabriel – the first time Arsenal have conceded in 508 minutes.
In the second-half, defender Rob Holding spurned a great chance to equalise, sending an effort over the crossbar after the ball bobbled up for him in the Southampton box.
Former Arsenal player Theo Walcott then ballooned over a decent chance at the other end before Fraser Forster did well to prevent Eddie Nketiah from levelling.
Arteta’s last throw of the dice was to bring on Alexandre Lacazette but they never looked like finding the goal to take the tie into extra-time.
