Former Arsenal midfielder Conor Henderson retired at 33 due to persistent knee issues and has now returned to the club as a youth coach.

The one-time Republic of Ireland U21 international, who made his sole senior appearance for Arsenal in a 5-0 FA Cup win over Leyton Orient in 2011, saw his career trajectory altered by injuries before moving abroad in search of regular football.

Henderson, once regarded as a promising playmaker at Hale End, suffered a serious knee ligament injury in 2011, just months after his first-team debut under Arsène Wenger. The setback sidelined him for the entire season and hampered his progression in a midfield packed with competition. After a brief loan at Coventry City, he was released in 2013.

Following his departure, Henderson struggled to find stability, playing for Hull City, Crawley Town, Stevenage, and non-league sides Grimsby Town and Eastbourne Borough.

In 2017, he moved to Bulgaria, where he enjoyed the most consistent spell of his career with Pirin Blagoevgrad, helping the club win promotion. It was a move that came when his career seemed to be stagnating, but saw him make 67 appearances, scoring seven and assisting 14.

He played in the Bulgarian First and Second Leagues, experiencing both promotion and relegation. His performances earned him a return to the top flight in 2021, and he remained in Bulgaria until 2022, before retiring due those ongoing knee issues.

“It was the most football I played in my career,” he reflected. “There were challenges, but looking back, I am glad I did it. I am grateful for the years I had in Bulgaria, as I developed as a person as well as a footballer.”

Henderson has since transitioned into coaching, now working with Arsenal’s U14s after a spell with the U12s. “I’m glad I did it. It feeds into the work I do now at Arsenal, helping young players develop, learning resilience and inner strength.”
