Arsenal fans collectively mention the "right-back curse" after the 9-minute shock.

The young Arsenal star was forced off the field injured only nine minutes after being substituted, intensifying supporters' concerns over a trouble-prone role.

Arsenal continues to receive bad news on the right flank in the friendly match against Real Betis in Dublin, as young talent Louie Copley had to leave the pitch due to injury.

The 19-year-old player was only on the Aviva Stadium pitch for nine minutes before the incident. While trying to shield the ball from a Real Betis player, Copley's studs got caught in the turf, causing his leg to twist unnaturally.

Copley immediately fell to the ground and needed medical attention from Arsenal's staff. The youngster was later able to limp off the field with assistance from medical personnel. According to initial images, Copley appears to have a knee issue.

The injury to the 19-year-old player quickly caused the Arsenal fan community to worry. Many fans believe that the club's right-back position is "haunted" by a series of ongoing fitness issues.

One fan commented: "Our right-back position might be the most cursed in football. Even when an academy midfielder is placed there, he gets a knee injury".

Another fan lamented: "It's such a shame for Louie Copley. The injury doesn't look good. This was supposed to be a big chance for him to show his ability".

Some opinions suggested Copley might have twisted his knee, while many expressed disappointment because the young player was on the verge of making an impression during preseason preparations.

Arsenal fans' anxiety grows even more as the team faces personnel difficulties at right-back.

Jurrien Timber is currently sidelined with a groin injury. This issue caused the Dutch international to miss the final two months of the Premier League season and also prevented him from participating in the World Cup. Timber faced further setbacks in July and had to return to London from Arsenal's training camp in Spain.

Previously, Ben White also had to take a long break due to injury. The fact that right-back options keep encountering problems makes Gunners fans haunted every time a player assigned to that area goes down.

Copley's injury capped off a forgettable evening for Arsenal in Ireland. The Gunners not only lost another player but also suffered a 1-3 defeat against Real Betis.

Arsenal has not yet announced the specific extent of Louie Copley's injury. The 19-year-old will likely undergo further tests to accurately determine the condition of his knee.
