Pochettino got Chelsea from drowning to the relegation zone to finish in a comfortable position on the table even though they had a poor form and they almost finish above Tottenham if not for some draws they had in the closing part of the season I think that was when they became ruthless and stronger in holding the ball.
With all these done by Pochettino in the Chelsea squad I think they should give him another opportunity to lead the squad next season after all he has gotten that connection with both the players and the fans, even if some of the fans don't buy the idea of him staying. To me if they bring another coach immediately after Pochettino leaves the side I feel the Blues will struggle again and this time it would be worse, but let's wait till Thursday if the Chelsea board would give him another go with the club.
