A coach’s tactical adjustments during matches are vital. A notable case was the 18th round of the Premier League, when Chelsea lost 1-2 at home to Aston Villa in a comeback, resulting in the Blues going two league games without a victory.

After 12 rounds of the Premier League, Chelsea remains in second place, 6 points behind top-ranked Arsenal and 1 point ahead of Manchester City. However, entering December, Chelsea’s Premier League form collapsed, with only 1 win in the last 6 matches, recording 1 win, 3 draws, and 3 losses. This slump has dropped Chelsea to fifth place, level on points with sixth-placed Manchester United and even trailing struggling Liverpool by 3 points. Their recent performances have been truly dismal.

Chelsea’s poor form in December has seen the team fall from title challengers to fighting for a top-four finish, while Aston Villa, who reversed the Blues’ fortunes, have risen from top-four contenders to title contenders themselves. Chelsea fans have pointed fingers at head coach Maresca, with many believing his substitutions in several games have been disastrous. Numerous supporters are even calling for a managerial change, arguing that the Club World Cup victory masks Maresca’s shortcomings in tactical skills and in-game adaptability.
It can only be said that Maresca has squandered a strong hand. Chelsea boasts the Premier League’s top defensive midfielder Caicedo, an excellent attacking midfielder Enzo, and captain James, who has returned to fitness, making the squad formidable. If Chelsea ends the season empty-handed, some key players may consider leaving, as top talents always aspire to win trophies.
