In recent years, Sevilla have been experiencing some success in their footballing efforts. The club has been making strides in both the domestic league and the European competitions. However, there is still room for improvement in terms of their defensive solidity and the quality of their midfield.

The current transfer policy of Sevilla is aimed at strengthening the midfield, improving control and enhancing the January window. This strategy aims to address the weaknesses that they currently have in this area. They aim to improve their defensive stability by acquiring players who can contribute to the team's defense. Additionally, they aim to enhance their offensive capabilities through the acquisition of experienced players who can add value to the squad.

One of the key areas where Sevilla needs to focus on is their midfield. Currently, they have struggled with their ability to control the game, particularly against weaker oppositions. This has led to many of their opponents being able to exploit Sevilla's gaps in defence. To address this, the club will be looking to acquire players who can provide a more balanced attack. This could include players such as Marco Reus or Lucas Digne, who are known for their ability to play offensively.

Another area where the club needs to strengthen is their control over the ball. In recent seasons, they have struggled with their ability to break down possession and create scoring opportunities. This has been due in part to their lack of a strong backline. To address this, the club will be looking to acquire players who can help control the ball and prevent opposition attackers from getting into the box. This could include players like Jordi Alba or Nacho Monreal.

Finally, the club's January window should also be strengthened. With many of their rivals already having done so, it is important for them to make the most of their window. The club will need to look to sign players who can add value to the squad and take advantage of the opportunity to buy before the competition starts. By doing so, they can ensure that they have the best possible chance of winning the league and reaching the knockout stages of the Champions League.

Overall, the transfer plan of Sevilla is set to be a major improvement for the club. By focusing on their midfield, controlling the ball, and creating scoring opportunities, they can position themselves well for success in the coming season.
