When Frankfurt finished sixth place in the Bundesliga last season and as a result earned a spot in the 2013-14 Europa League, few expected much from Armin Veh's side on the continental stage. Their starting XI was rather ordinary, and critically, there was little depth to ensure the trainer would have fresh players available in every game.
Frankfurt exceeded all expectations by winning Group F with 15 points out of a possible 18. But the Adler have struggled on the domestic front and entered Saturday's clash with Dortmund in 12th place. After losing Tuesday's DFB-Pokal clash with BVB, 1-0, Frankfurt looked tired and not at all sharp as they faced Klopp's side for a second time in just four days.
The visitors were always going to struggle, but the way they capitulated in the opening minutes was proof that they were exhausted. The opener came after Sebastian Jung was dispossessed all too easily deep in his own half. The second followed a poorly defended corner kick; the third came from a needless penalty.
Within 20 minutes, the match may as well have been over: A very, very easy day at the office for BVB and one to forget for a very fatigued Frankfurt. On Tuesday, the two teams were near-equal. On Saturday, there was no comparison.
