Not sure for the Gunners but ...

We have been to St James' Park and Anfield for live games. For the former, tickets for general public are available online on the Club's official website between 2 to 4 weeks of match date. Anfield was a bit more trickier. If youre planning 2 months or more ahead, you can check with the local supporters club as we were given to understand that each local supporters' club is allocated 50 tickets. We did it the hard way - waited for the tickets to go on general sale, called up the special phone number listed on the Club's website and voila - 4 tickets in hand ! Caveat - we had to keep pressing the re-dial button for 4 hours to get through the ticketing office !!!

So, best advice would be to check Gunners FC official website. Am sure there will be a link on tickets. Don't go through unofficial websites - they are more or less legalised touts. A 35 quid ticket would be sold for 170 quid kind of thingie. Unless you enjoy being fleeced ...

Good luck.
