Think the 2nd leg at home was a advantage in years gone by based on a number of factors.
Less information was available about your opponents,crowd intimidation sometimes came into play,travel arrangements and accomodation were much more difficult and the state of pitches was a big factor as teams could have a advantage being used to their own.
Almost all of these things have been eliminated over time and it's maybe just because I'm a old **** that I remember these coming into play.
Tend to agree
Not buying that United are in the driving seat of their tie, if Sevilla score they are in trouble
