Just a quick question. I am in London now for work, first time abroad and they sent me on a short notice, so I couldn't plan before traveling. I know it's damn near impossible but is there anyway I could buy tickets to the West Ham game on 27th?

I am not entirely sure about the reliability of third party websites but if someone knows a way and can point me in the right direction, I'd be ever so grateful! I only need 1 ticket.

Apologies if this is off topic.
