Chelsea's defensive woes continue to plague the Blues as they face a serious threat in the form of a new signing from Ajax, who will be looking to replace injured defender John Terry.

The Blues have struggled to defend well this season, especially under manager Maurizio Sarri, who has been criticized for his inconsistent approach to defense. However, Chelsea has some promising signings on their books, including striker Cesc Fabregas, who is expected to help improve the team's defensive record.

Meanwhile, Chelsea's midfield struggles continue to hamper their chances of success. The Blues' best player, Romelu Lukaku, has missed most of the season due to injury, but he is expected to return soon. However, it remains to be seen how quickly he can regain his form.

In terms of goalkeepers, Chelsea have struggled to find a reliable replacement for goalkeeper Petr Cech, who has been struggling with injuries throughout the season. While Chelsea has had some success signing young defenders like Alex Song and Christian Pulisic, they still need to find a solid backup goalkeeper.

Overall, Chelsea needs to address its defensive issues if it wants to make a significant impact in the Premier League. With a new signing coming in, and a few key replacements on hand, the Blues should be able to compete at the highest level.
