I hate Europa League...90% of my expresses and single bets have lost today. I think all teams often play without enthusiasm in these international matches. They mostly think about their national championships and that makes bets really unpredictable.
I think it's the bigger teams who's place belongs in the champions league, but find themselves in the Europa league that play with lack of enthusiasm, it was really an issue in the past in this tournament, teams mostly even rested their players for their league games the following weekend.
I suspect that was why UEFA had to increase the price benefits, which includes an automatic qualification to the Uefa champions league the next season, a dream for most teams in the Europa league, as they hardly can ever make it through league qualification.
But in general, bets are unpredictable, be it in any footballing tournament, anything can happen.
