Actually Pochettino was not so bad he just didn’t meet up the conditions set for him that was what made him to be sacked. Looking at how the team performed and ended the season we all saw the improvement but for me personally i am not convinced because he still has the problem of being able to manage the players properly especially when there are lots of players to select from, he is still unable to select a preferred eleven and thats a major problem as a coach.
You reviewed everything Pochettino played in the last season and you decide to give him some accolades towards the end of the season. You didn't review the days he had opportunity wasted when Chelsea could have done better. The days they were stuck in the 11-10th place in the Premier League table for 6 weeks in row withoht any changes. If you owned Chelsea and you see a lot of potentials outside, you wouldn't be please to use him for second season.
They couldn’t keep him because he couldn’t meet the demands of the management but he still tried his best though.
That's exactly what happened, who knows if he has signed a contract with a condition to give the team a trophy, maybe FA cup, Premier League or promised to finished the season among top four but the result wasn't what they all expected and he was relieved from his job for another person to take over. Maybe things are going to change under management of Maresca.
