Arsenal legend Thierry Henry has admitted he has questions regarding the club's frontline.
The Gunners are challenging for the Premier League title after finishing second last season.
While they have been on a good run of results in recent months, Henry admits their attack may lack compared to rivals Liverpool and Manchester City.
If you take the front three [Bukayo Saka, Gabriel Jesus and Gabriel Martinelli] that have been playing the last two Premier League games and more often than not," Henry told CBS Sports.
You think of Leandro Trossard on the bench.
But if you think of the front three of Man City, Liverpool, Aston Villa and Tottenham and look at our front three. You can take it two ways.
"You are saying, as an Arsenal fan, you are (second in the table) and the front three that maybe didn't play all the time. We are nine goals (in total so far this season), so if we ever start to score goals, then we can win this league.
Or you are saying, if they stay at the same pace, then it's going to be difficult to win the Premier League. You need to find a way to score goals and kill teams. I hope as an Arsenal fan, they can reach that level."
