Good question, hadn't thought of that.
Looked it up, we've earned £775,000 in prize money so far, guaranteed another £500,000 even if we were to lose to ManU. If we were to win it'd be £1m and then the final winners get another £2m, runners-up £1m.
Useful money but not a patch on the Champs League.
The problem with going for the Europa next season, which as has been said we'd have a chance of winning with a bit of luck and form, is that it'll take nineteen games to achieve that. That's an extra half season, with our squad size? League form would definitely suffer. Better for me to go into the Champs League group stage, earn the money, get knocked out so we can concentrate on our league position and use the money to increase squad size and quality for a serious go at Europe in the following years. Simple .
