Yes of course, during the Abramovich period, Chelsea was known to be very strict with its manager. The decision to fire a manager is often made quickly if expected results are not achieved. This was done as an effort to ensure the club remains competitive at the highest level and wins trophies consistently. This philosophy has brought much success, including several Premier League titles, the Champions League and other domestic trophies.
However, it should be noted that each club has different policies and managerial philosophies. Some clubs prefer to give managers time to build a team and achieve long-term results, as seen at Manchester United with Erik Ten Hag. This approach can provide stability and sustainable development although it requires patience and time.
During Abramovic era the manager keep existing around more than one until two season without sacked them such as did by Todd Boehly era because some manager leaving their position without one season over. Chelsea faced difficulty return back to be big four team of premier league since acquisition by Todd Boehly and never yet participants in Champion League or Europe League competition. Chelsea under Todd Boehly era made more interventions in recruiting players, even Pochettino had to leave his position after not being given the freedom to recruit new players.
Build up one team with full youth player need time for development and I think Chelsea owner more patience waiting for giving opportunity more longer time to manager find right tactician. In this season Chelsea will perform in UEFA Conference League and its opportunity after absent last two season with European competition.
