The Gunners legend believes if Arsene Wenger had picked full strength sides, they would have won it a couple of times.
The competition was often viewed as an opportunity for Arsene Wenger to field weakened squads over the years, with the manager often electing to go with sides full of youngsters in whichever games the Gunners drew.
It has been evident for a number of years that Wenger sees the competition as a secondary one in which he can blood his youngsters, with the likes of Jack Wilshere and more recently Joel Campbell getting their breaks in the tournament.
And Henry says it was an unwritten rule at the club that Wenger would go with the kids.
“It was kind of an unwritten rule that we knew he [Wenger] was going to play the kids,” he told Sky Sports.
“People might say it’s your prerogative because nobody asks you play the youngsters in this competition, it was kind of a weird one. It’s the first trophy you can win, it gives you a taste of winning a maybe you want some more.”
Full strength Arsenal could have won it a couple of times
The forward insists, however, that had Wenger ever decided to go with a full strength side in the competition, they would have won at least a couple over the years.
The Gunners haven’t won the tournament since 1993, meaning Wenger has never won the competition as Arsenal manager, despite having enjoyed huge success in both the league and FA Cup with them.
That is principally down to his use of the youngsters, and Henry says if first team regulars like himself, Patrick Vieira and the rest had all started, they would have taken the trophy.
“We never really had a go with the team we had at the time, with the best eleven we could put on the pitch,” he added.
“I didn’t actually play that competition. We never really had a go. I will still maintain that if we had had a go at it with a full squad, we would have had a couple.”
