If Thomas Tuchel wants to become the Chelsea boss with the most matches managed since Roman Abramovich bought the club in 2003, he is over halfway there. The end goal is much bigger than that, but to achieve the long term goals, it's a good start.
There are currently only three names in front of him, which tells you a story in itself, as Tuchel has only been in London since February 2021, and barring a massive early season collapse, he will pass Carlo Ancelotti and Antonio Conte by Christmas.
That would still only put him third in the list though, Jose Mourinho sits comfortably in first and second place for games in charge since June 2003. His first spell from June 2004 until September 2007 is the second longest at Chelsea since the 1980s.
