Why a fascinating Champions League final awaits, whether Real Madrid play Chelsea or Atletico Madrid

A look at why a match up between Chelsea or Atletico Madrid and Real Madrid will make for a great showpiece in Lisbon

Chelsea and Atletico Madrid are just 90 minutes away from reaching the Champions League final (or 120 if the score stays 0-0 at Stamford Bridge tonight).
