The lads had set their sights high and implemented many things well.

We created plenty of chances today, but in the end, it was always the little things that were missing," Eta said after the match.When she emerged from the tunnel before kick-off, nearly every camera in the stadium was pointed at her."I was the centre of attention. It's not about me, it's about football," she stressed.While Union are 11th in the standings, Wolfsburg are in the relegation zone and six points from safety.Leipzig with crucial away winFrankfurt suffered a setback in their fight for a spot in Europe and are currently empty-handed in seventh, but Leipzig took crucial three points as they bid to qualify for the Champions League.Hugo Larsson levelled for Frankfurt in the 34th after Yan Diomande had broken the deadlock for Leipzig in the 27th.But Antonio Nusa put Leipzig ahead again in the 70th and substitute Conrad Harder needed only two minutes on the pitch to seal the win for the guests in the 81st.The top four qualify for the Champions League.
