I wouldn;t say they flipped, when Barcelona was tiered against Frankfurt; the bookies supported outrightly that Barcelona will be knocked out of the europa league with the odds ratio; i also personally watched the tie and concluded that Frankfurt was a core favorite. The big question meanwhile is that would Rangers be able to replicate their form on the biggest stage in the final of the europa league ?
I don't recall that. When Barcelona played Frankfurt, Barcelona was the favorite by a huge margin. They were also the favorite to win the cup as soon as they entered it. Almost everybody expected Frankfurt to get knocked out in their 2nd leg, when they showed their amazing performance in their away game.
But similarly the Rangers knocked out some favorites like Dortmund and Leipzig. I do expect a pretty open game
Frankfurt have eliminated the team who are favorites in the Europa League, since meeting Real Betis, Frankfurt is not seeded. Surprisingly Frankfurt managed to score 2 goals at home to Real Betis with the final score 2-1 for Frankfurt's victory. In the second match Frankfurt drew 1-1 with Betis, while making Agg 3-2. Frankfurt incarnated like the team that killed the champion favourites, Barcelona and West Ham must recognize the greatness of Frankfurt in the Europa League stage.
Now that Frankfurt is in the final, Rangers will be Frankfurt's last opponents in the Europa League. Frankfurt must continue their sweet journey in order to lift the Europa League trophy while maintaining their chances of appearing in the Europa next season.
