The winter transfer window is typically the best opportunity for teams to adjust their squads, primarily targeting those that have underperformed in the first half of the season, such as Premier League clubs like Manchester City and Manchester United. However, for a team like Liverpool, which is leading both the league and the Champions League, it may seem unnecessary to strengthen the squad. Nonetheless, Liverpool is facing challenges that are not as straightforward as they appear. They will also be competing on three fronts in the second half of the season - the league, the Champions League, and the FA Cup. Whether the existing squad can cope with this multi-front battle is a question that needs to be addressed by manager Jurgen Klopp.
Every season, there are teams that lead in the first half but collapse in the second due to injuries and reduced personnel. Liverpool has experienced this before, with their performance suffering due to injuries. Currently, Liverpool's squad is relatively complete, and with the return of Konate and Bradley from injury, only Gomez and Kjellgren remain on the injury list. It seems that the squad is indeed well-equipped. However, Liverpool still faces issues regarding the renewal of core players' contracts, the future of Kjellgren, and the backup for the left-back position.
The contract renewal issue for key players is not something that can be resolved quickly, especially with little progress in the negotiations for Alexander-Arnold's renewal. The renewals for Salah and Van Dijk are also uncertain, which could potentially affect Liverpool. While Liverpool is reportedly confident about renewing Salah and Van Dijk's contracts, the situation with Alexander-Arnold is more complicated, with negotiations far from reaching an agreement. Whether Alexander-Arnold's renewal will impact the team's dressing room remains a concern for Liverpool.
Regarding Kjellgren, the issue is not significant compared to the tight midfield and defense. Liverpool's front line is competitive, with enough options available. Even if Kjellgren plays, it would likely be in a substitute role. Since joining Liverpool, Kjellgren has not had much playing time, and according to multiple media reports, he might choose to return to Serie A during the winter window. However, the second half of the season will have more intense matches, and if Kjellgren stays, it would provide Liverpool with more choices. It is hoped that Kjellgren will remain.
The left-back issue may not emerge this season but could become a challenge for Liverpool in the future. Robertson can still maintain his competitiveness in most games, but occasional mistakes could pose problems for Liverpool. Ensuring that Robertson has a competitor and a substitute is crucial and will influence Liverpool's winter transfer strategy. Liverpool currently lacks suitable candidates for this position, and without new signings, they can only hope that Robertson does not encounter any issues. Therefore, Liverpool still has problems to solve in the winter window, and whether they need reinforcements depends on whether the club wants to address these issues during the winter window or wait until the end of the season.
