Die Werkself had more problems in the defensive transition due t0 their use of limited fullbacks. This may seem stupid as surely not having your fullbacks high up the pitch would mean that you are more defensive solidly, especially being less vulnerable in transition. However, the fullbacks staying back meant that Bayer’s double pivot had to play high up the pitch to give them good attacking numbers. This meant that there was always a huge space centrally in front of the Leverkusen defence when Wolfsburg were breaking so their counterattack couldn’t be held up, so their defence had to retreat at pace. This is when problems are caused.
