Frankfurt marched on in Europe on Thursday by forcing an own goal in extra time to seal a 1-1 draw at home to Real Betis, earning a 3-2 aggregate win in the last 16. The ball bounced into Betis' goal off away defender Guido Rodriguez in the 120th minute to put hosts Frankfurt through in dramatic scenes.
Sevilla are fifth in Spain's top flight with Barcelona third, inspiring Glasner to challenge his side before their mouth-watering home leg on April 7. "I'll say casually and provocatively: if you can progress against the fifth-placed team in the Spanish league, you can do the same against the team (Barcelona) who are third," urged Glasner.
Frankfurt sports director Markus Kroesche said he took heart from seeing Barcelona squeeze past Galatasaray with a 2-1 away win in their last 16, second leg tie.
