Till half of the season, is the time I think the management of Chelsea will expend before considering finding a replacement for Pochettino. It isn't his fault really, but if I must say, new players have to adapt to the new environment and style of play as well as team phsychi before being expected to deliver much in return.
The team needs a very creative player who can really be calm with the ball and link up the attack and midfield with dribbles and accurate passes. Otherwise what we have witnessed in their style of play so far will be replicated in their other competitive games.
If indeed Chelsea management has plans to replace Pochettino as coach, my only question is, how long will Chelsea have to replace the coach repeatedly without any changes?
I saw from last season that Chelsea changed their coach several times but still had the same player performance without any improvement unless Chelsea management gave each coach one season opportunity to get the best strategy or if you really want to build Chelsea stronger, at least look for a new coach who has a lot of experience in all European league teams or major competitions and provides a large enough offer for the prospective new coach so that opportunities for improvement will be more visible when experienced coaches manage this team players. I will not blame the Chelsea players this time because if the players are skilled but not have an experienced coach it will be very far from expectations because skilled players need strategies from the coach.
