Of course you are not saying Pochettino is a bad coach, but in the end you are just conveying the impression that Pochettino does not have the ability to make Chelsea better or even compete in the top four. If Pochettino hears about it then I think he'll be furious, of course. Lol
Chelsea fans must be patient to see the process that Pochettino is going through in building the quality of his team in this relatively new season. Their statistics are not good, but improvements will continue to be made so that Pochettino's plans are truly successful. Nothing is impossible in football, in fact no one really believed Newcastle could qualify for the Champions League this season when they started last season.
I'm Chelsea fan and I would urged my fellow colleagues to exercised patience because EPL is still early and we have a long way to go. Chelsea fans are running out of patience at Stamford Bridge, losing to Nottingham Forest spelled out the poor performance of the club and unveiling more struggling circumstances for them. Mauricio Pochettino is new to the system and it will probably take some time before he finally get acquainted with the entire system. Chelsea is an elite club and they expects the very best from the new coach, I wouldn't blame Pochettino for the current poor condition of the blues, they will definitely pass this poor phase.
