Thomas Tuchel's long-term tactical changes at Chelsea didn't really go far beyond playing three at the back. It was a radical move at the time having spent the large part of two and a half seasons with a rigid 4-3-3, though a back three was used on occasion under Frank Lampard.
From the get go it showed the tactical chameleon that the German had become known as. His use of Callum Hudson-Odoi as a wing-back and Cesar Azpilicueta being moved to centre-back once more was inspired and saw a massive upturn in results.
For Tuchel, there wasn't much more to follow in terms of consistent trends of tactical moves. Sometimes he moved from 3-4-3 to a 3-5-2, other times there was a more expressive 4-2-2-2 sprinkled in. Movements between the forwards shifted from a 3-4-1-2 into a 3-4-2-1 but that was really the limit on the large part.
