The concern I have...
BBC Sport's chief football writer Phil McNulty has been answering your questions.
Sam asked: Do you think Arsenal could solve their attacking problems by bringing in a more prolific left winger, or more creativity in other positions? Or do they need to be a striker?
Phil answered: I think Arsenal have lots of creation in the wide areas. We have seen it from Bukayo Saka this season and from Gabriel Martinelli when he scored at Chelsea yesterday.
I just think they need that recognised goalscorer, not only for the goals but to also give them an attacking focal point, a point of difference. Gabriel Jesus has not done enough and is injured too often and, while Kai Havertz is a talented forward who scores goals, I still think they need that recognised marksman.
It is a concern I have about Arsenal for the rest of the season.
