Arsenal legend Thierry Henry says the Gunners need four top-quality players to be on the same level of champions Chelsea.
Arsenal have only signed Petr Cech from Chelsea during the summer transfer window but are expected to add more players before the end of the transfer market.
"That team, I think, has great mentality, top-quality players and match-winners," Henry told Sky Sports.
"I still think they need four players to get closer to Chelsea.
"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.
"Olivier Giroud alone there as a natural-born striker, it is difficult, because they say when he does not score, it is very difficult.
"Hopefully Theo Walcott could be the answer. You have a guy who you did not think was going to play as a striker, although he has been the talk of the town for a little while, him playing as a striker.
"You know some people still question Arsene Wenger, but I still think that Arsene has the right attitude and fire; the fire in his belly to try to make sure that team can win another title."
