a team can survive and achieve success always through a long process, not instant and it all requires solid cooperation between players and as long as Chelsea doesn't always change coaches, at least give the new coach the opportunity for 2 seasons, we can see how it develops.
We can see the example of a team like Man City which was initially replaced by a new coach but maintained that there was always improvement in every season and last season managed to get a treble winner. with this example, it can provide innovation to other teams to gain that experience and put it into practice in their own teams and it's natural that you dont blame Pochettino because he is a new coach and needs a long time to be able to bring his team to a higher level.
It is true that Pochettino was unable to make Chelsea appear competitive in the first half of the season, but he still has the opportunity and hope to appear competitive in the second half of the season. Anything is very possible, especially since Pochettino is known as one of the coaches who has better experience in the Premier League with Tottenham.
