Assuming I can get tickets not sure if i'd rather want to go to atleti v Barca / Real (home game)

So, the fixture list is out and I knew we'd be playing them in Oct / Nov (always the case isn't it...)

Can't afford going to both (as I live in the UK and it's about £150 a pop - flights, tix, hotel etc) so I want to go to one. I regret the day I could have gone to the game where we beat them 4-0 at home but instead went to watch my local team Cobblers (Northampton Town) in a 0-0 draw I think.

I assume against Real would be better in terms of atmosphere but it's closer to xmas so not too sure.

Any suggestions?

:-)
