Laia Cervello Herrero (Barcelona): Flick’s team have been hurt by a lack of concentration at times this season. This is a young team who have occasionally been overconfident against seemingly weaker teams.
Although that is unlikely to happen against Madrid given who are their rivals.
Another issue is Flick’s high defensive line, which allows them to be more attacking but means they take risks at the back. Unforced turnovers could lead to some dangerous counter-attacks from Madrid.
Guillermo Rai (Real Madrid): You might be tempted to say morale after Madrid’s Champions League elimination and Copa del Rey defeat, but their defence has been the biggest headache for Ancelotti this season.
A lack of intensity, tactical problems and several injuries in the back line have hurt Madrid.
Given they lost 4-0, 3-2 and 5-2 against Barca in La Liga, the Copa del Rey and the Supercopa, they will need to do better here.
