The Gunners improved immensely towards the back end of last season, completing an impressive eight-game winning streak in the league and finishing the campaign with another FA Cup success.
However, many Premier League observers still feel they need to improve the spine of the team in order to challenge for top domestic honours, with a new goalkeeper, midfielder and striker in particular cited for improvement.
So far this summer, Arsene Wenger’s side have at least solved one problematic area – signing Czech Republic international Petr Cech from London rivals Chelsea.
Henry, however, feels his acquisition alone isn’t enough to turn his former club into genuine challengers and told reporters that four further additions need to be made.
"I still think they need four players to get closer to Chelsea,” the Gunners legend was quoted as saying by the Daily Star.
“I compare it to my generation, I knew, for example, when I first arrived at Arsenal that if I was not performing after an hour, Dennis Bergkamp was on the bench sometimes or Kanu or Sylvain Wiltord or Davor Suker. Whoever it was, I knew I had an hour to perform."
Do Arsenal need further attacking additions?
Thierry Henry’s comments suggest he’s not fully convinced by Arsenal’s frontline, an opinion he shared in the Sky Sports studio towards the end of last season, which subsequently caused quite a stir.
But where can improvements be made? In Alexis Sanchez, Theo Walcott, Mesut Ozil, Santi Cazorla, Aaron Ramsey and Alex Oxlade-Chamberlain, the Gunners have a wonderful set of attacking options.
The centre-forward area is the major one, but Olivier Giroud’s presence gets the best out of his fellow midfielders. The France international has superb link-up play, and he knows where the net is.
Would replacing him with Karim Benzema be an upgrade? The Madrid ace may be more prolific, but it would be blinkered to assume he’s better than Giroud in general link-up play and team work.
