Former Arsenal player Paul Merson has claimed that "serious questions" need to be asked if the Gunners are not challenging for the Premier League title come April.

Arsene Wenger's side had a positive campaign in the 2014-15 season by finishing third, two spots behind champions Chelsea, and winning the FA Cup.

The North London outfit have been quiet in this summer's transfer window so far, but have recruited goalkeeper Petr Cech from Chelsea for around £11m.

When asked by Sky Sports News about Arsenal's title prospects, Merson said: "The thing is, Chelsea have been there and done it, whereas Arsenal haven't, and that is why if you see the bookmakers' prices Arsenal are a lot longer than Chelsea and City. And that is because they have not been in that situation before.

"However, if they are not contending come next April, then there have got to be serious questions asked, especially as they have bought a very good goalie."

Arsenal will face Chelsea in the Community Shield at Wembley this Sunday.
