This is a very tough task where Pochettino has to coach Chelsea when it is in its worst phase.
With the replacement of several players it might be easier for Pochettino to improve Chelsea's performance but the question is whether Chelsea can spend a larger amount of money to be able to transfer players.
But if they are willing to sell some players and the proceeds from the trade are used to buy other players then Chelsea can save a little on spending on player transfers.
Todd has chosen Pochettino as the new Chelsea coach and Pochettino has agreed, meaning that whatever the risks are and no matter how hard the work, he must be able to take responsibility and do something to make progress. Pochettino is currently overhauling Chelsea, and the first step he took was selling some of his players who were deemed unable to make a significant contribution to the team, then buying new players with more potential and promise. Reportedly this is to reduce expenses that swell. Pochettino is believed to have discussed several potential targets with Chelsea in the upcoming transfer window, and he already has a clear vision of what could happen during the summer transfer window. I hope that with all his coaching experience, he can make Chelsea even better in the Premier League in the future.
Pochettino the new Chelsea coach is not starting afresh or starting from worst. If you discover last season that Chelsea was struggling with form and losing all their matches. They were also signing good players. So it is correct to say that Chelsea has good players that they have signed, but the problem was that there was no chemistry between the players and the Coach and management. So it is now the function of Poch to put everything together to give Chelsea a successful season. The rebuilding started last season not this season.
