In Baku, Azerbaijan tonight - two London sides will contest this game, nearly 3,000 miles from home.

Chelsea will play Arsenal and fans are having to make horrendous journeys to the game - because of the few flights available.

Some are driving (for 5 days!), and the route isn't easy.

A win for Arsenal would put them in the Champions League (and earn them nearly £100 million) next season; Chelsea have already qualified.

Venues for major club finals are chosen two years before - when the participants are unknown.

These London sides have just both drawn short straws...
