Hopefully Todd Boehly will not regret his decision to stop Mauricio Pochettino as one of Chelsea's best coaches. I don't know for sure how Chelsea will be next season. Does Chelsea have a new coach who can improve Chelsea's performance and provide victory next season? If Chelsea always does this then the possibility of Chelsea winning will be very difficult to obtain.
I don't know who else could best fit in to pochettinos space as he leaves Chelsea, he was already at the verg of redemption for Chelsea moving them from the struggling State to a progressive State but then it appears be isn't moving quick enough for the Chelsea management and so they dimmed it for to relieve him of his job which I hope it doesn't get to be detrimental to them as I doubt if there's actually a perfect replacement for him at the moment.
A few have been say they feel pochettino isn't showing a winning mentality which is what they desire for the progress of the team but then a careful look at his performance this season and you will agree with me that he's done so well for a coach who's trying to get a team back on their feet and is more like one at the building stage of the team but they aren't seeing it in that light, he managed t get a very productive results in all his encounter with all the top 6 teams in England and this was why he has been able to finish at top six and not nine or eight.
Even if Chelsea get a new coach I doubt he will be able to take them to glory next season such that they will be able to lift a trophy, they would have had better chance with pochetitino but they don't seem patient enough with the stage he has gotten to so they would want to get a machinery who's probably faster with the building stage to getting results.
