Inquiry about tickets

I'm going to be in Liverpool on Tuesday Evening with my son. Can anyone tell me what my chances are of buying tickets (at a reasonable price) outside the grounds. I'd appreciate any advice

U will get a couple of tickets, the price will obviously depend on how near to kick off u manage to hold out!!!

Good luck and don't go spending too much...

Oh and my ethical stance is I don't agree with ticket touting.  :oops:
