Chelsea problems appear to be caused by more than just bad investments. Despite significant investment, they continue to perform poorly, placing tremendous pressure on the owner. Fans are discouraged as a top four finish appears to be getting harder to come by. Todd Boehly, a big investor, may become frustrated by ongoing losses, endangering Pochettino employment. Pochettino needs to develop a winning strategy nevertheless if he wants to avoid being the third coach to be fired. It is critical to recover from the team injuries and strengthen the bench. A turnaround can be imminent if the board accepts these difficulties and gives Pochettino time.
Alot is going on in the team currently, from the poor investment, to the injury crisis, to lack of confidence level of the team and that's why the team is suffering badly lately, and to make the whole situation worst, one of their key players Malo Gusto got booked with a red card in the match against Aston Villa, which puts more pressure on the coach due to lack of options, well Chelsea dominated the game and created some chances but couldn't convert to a goal due to lack of a good finisher.
Pochettino needs to think fast because they'll be facing Brighton in their next match at Stamford Bridge, but they're going to get it very tough, because Brighton have been in a very good form this season, and if he continue losing he might end up losing his managerial role very soon.
