Liverpool suffered a disappointing 1-0 defeat to Nottingham Forest, marking the end of their perfect start to the Premier League season. Captain Virgil van Dijk criticized the team's performance as 'unacceptable,' highlighting issues with being rushed and losing too many second balls, which allowed Forest to capitalize on their chances. The defeat was particularly bitter as it was Arne Slot's first loss since taking charge, and it marked only Van Dijk's third defeat in 101 home league games. Van Dijk emphasized the importance of consistency moving forward and insisted that losing at home cannot become a regular occurrence. The team now looks to rebound quickly, with a Champions League match against AC Milan on the horizon. Despite the setback, Van Dijk remains confident in the squad's ability to improve and learn from this 'reality check.'
