What 'could hurt' Arsenal?

BBC chief football writer Phil McNulty has been answering your questions.

Richard Peel asked: Are Arsenal really so reliant on set-pieces, and if teams work out how to stop them are they in a fight for the top four rather than the title?

Phil answered: Hi, Richard. I really don't think Arsenal are over-reliant on set-pieces, they are just very good at them.

If you look at Arsenal's team, lots of goals can come from elsewhere, they just happen to be scoring from set pieces at the moment.

What I do feel, however, and I have stated this on several occasions, is that Arsenal's failure to sign a recognised 20-goals a season striker could hurt them over the course of the campaign and I still feel that.

I still think they can mount a title challenge but they have a real fight on their hands with Liverpool in front and Chelsea looking so good. For further insight on this question, I will direct you to an excellent piece by my colleague Sean Kearns on this very subject.
