Hi, I am travelling to Barcelona for el clasico in March and am trying to get 2 tickets for me and my son who is 10. I knew it wouldn't be easy but some of the prices that exchanges are selling for are ridiculous; if anyone can recommend a better option I would be grateful.

We are both Liverpool season ticket holders and play Manchester United at home on 21st March, I would be happy to consider an exchange of tickets if anyone may be interested in coming to Anfield, we could meet on the Friday as we don't travel until the Saturday.
