Several key players, including Trent Alexander-Arnold, Caoimhín Kelleher, Jarell Quansah, Luis Díaz, and Darwin Núñez, departed the club, while others like Harvey Elliott and Vitezslav Jaros joined on loan for the season.

Despite their strong start to the season, with four wins from four games, Liverpool's performance is not yet at its best. The team is still building chemistry and working towards competing for the title.

"All the players who left made a significant contribution to our team," Alisson said. "They brought goals, energy, and a fighting spirit. We miss them."

However, the players who have joined the team are also making a positive impact, with many showing great quality and potential. Alisson acknowledged that the team needs to improve and is working towards achieving their goals in multiple competitions.

Darwin Núñez, who left for Al-Hilal, scored a goal in his second match for the club, while Luis Díaz, now at Bayern Munich, has scored four goals and provided two assists in just five appearances.

Despite their excellent form, Liverpool's lack of certain players is noticeable, and Alisson's comments suggest that the team is still adjusting to the changes. As the team continues to build chemistry, they could become a formidable force in the league.
