The back five with three central defenders and two wing-backs has become a staple of the Chelsea team since Thomas Tuchel’s arrival last January.
However, with the team hit by injuries to key players such as Ben Chilwell and Reece James, the gaffer has hinted at a system change. He said of using a back-four in the future: “Yes, but it has to make sense.
“I always told you, why should we change? It’s successful and suits our players. For a back three you need three central defenders. For a back five you need three and two wingbacks. We simply did not have the players available to play a back five now.
“The differences are not that big. If it suits the players and the positions, which it did for this game, we should be always open for it.”
“The most important is how we play in the system and how lively we play, how courageous we play within the structure. Structure is important for us. We protect ourselves in the structure.
“Structure can help us to be stronger as a team but the most important will always be like how the players live up to it.
“It suited us good for this game [Spurs], we did good. It can stay an option but no matter what we play, how we play is more important.”
The Blues’ primary wing-backs are out injured for the near future and Thiago Silva is currently isolating after testing positive for Covid. It’ll be interesting to see how Tuchel changes the system to get the best out of the remaining players now.
