The main prob I am concerned about is the way uefa is carving up the cl to suit the top 4/5 leagues,and leaving all the rest, to compete for the remaking few places!!!!like you say the away goals does make you try for a result of sorts,hhI've always liked the away goals rule, think its fair and encourages the away side to not park the bus.
Like the good old penalty shoot-out, they are heartbreaking when you lose them but is the only way to deside cup games but in Europe I feel the away goals rule is the best way to go
