Following his appointment as Chelsea boss in January, Thomas Tuchel implemented the 3-4-3 system, which helped the Blues defensively.
With the 3-4-3 system, the Blues were able to achieve a top four finish and also win the Champions League.
It seems Tuchel might be set to dump the 3-4-3 system this season after trying out a new formation during preseason training and the friendly victory over Peterborough.
Tuchel trialled a 4-2-4 formation, which can also be recognised as a 4-2-2-2, in the second half of the pre-season friendly hinting that Tuchel may have plans to implement a new brand of football.
Tuchel used the formation during his time at Paris-Saint Germain.
Would you want Chelsea to use a 4-2-4 formation next season instead of the 3-4-3?
