Chelsea's tactical training is one of the most important aspects of their success, and it has been enhanced through coherent squad development. The club has always had a strong emphasis on developing young players, which has helped to build a solid foundation for their squad.

One of the key elements of Chelsea's tactical training is the use of individual player analysis. This involves taking a close look at each player in the squad, assessing their strengths and weaknesses, and identifying areas that need improvement. By doing this, the club can tailor their tactics and strategies to suit the specific needs of each player, ensuring that they are able to perform at their best.

Another important aspect of Chelsea's tactical training is the implementation of a clear and consistent game plan. This means that every match is planned out in advance, with specific tactics and strategies being implemented based on the opposition's strengths and weaknesses. This approach helps to ensure that the team is well-prepared for each game, and that they are able to execute their plans effectively.

Coherent squad development also includes the use of data analytics to help identify potential weaknesses within the squad. This allows the club to make informed decisions about who should be playing in certain positions, and how they should be used in those roles.

Overall, Chelsea's tactical training has been greatly improved by the implementation of coherent squad development. By focusing on individual player analysis, implementing a clear game plan, and using data analytics to identify weaknesses, the club is able to develop a squad that is well-equipped to compete at the highest level.
