Definitely yes to the Europa League.
For one thing, European competition makes us a more attractive club to players. You can only go so far when it comes to persuading players to come here (such as the talk of the fans and the stadium, comments from current/former players etc.) but the lure of the Europe is that little bit extra which will help to convince a player to sign for you ahead of others.
I definitely like the "glamour" involved too. We had such great adventures in the UEFA Cup/Champions League so would love to see the European nights back at St. James' Park.
