#2 David Luiz
David Luiz has started every single game in the Premier League. This system is very suitable for the Brazilian because of his creativity. He is known as a defender who loves to have the ball at his feet, and very often he is responsible for the game creation in 'Sarriball'.
However, not all is that simple. His defending skills are on a very low level, and that has caused many goals this season. In addition to that, Luiz's contract expires this summer, and the maximum Chelsea offers for players older than 30 is a contract for one year. The latest reports say David Luiz won't sign that type of contract extension.
With all this in mind, it's time for Andreas Christensen to get his chance. The Denmark international is very good with the ball at his feet. What separates them is Christensen's discipline in defence. It's time to give the Dane more playing time in the league.
