I'd say Sunderland V Newcastle and Celtic V Rangers have a better atmosphere. They are crazy in those derbies though.
For the love of god though, I hope it doesn't end up like Besijktas and Galatasary though.
Im Turkish so this is a big match for me. I'm a Galatasaray fan and hate Fener, Obviously Galatasaray will win due to the fact we have eboue at back, and Drogba and sniejder up top/
