Chelsea manager Thomas Tuchel has admitted he made a tactical mistake as his team suffered a first-leg defeat to Real Madrid in the Champions League.
Karim Benzema scored all three of the visitors' goals in a 3-1 victory, becoming the first player to score a European hat-trick against the Blues in the process. The 34-year-old also set a record for goals scored by a French player in a single Champions League or European Cup season, after Just Fontaine's high mark had stood for more than 60 years.
Tuchel was disappointed in the levels shown by his team, who failed to recover after a weekend Premier League defeat at home to Brentford. However, the German was also willing to take some of the blame himself for how he lined his team up defensively.
