In Chelsea, Pochettino is not guilty of the bad performance they get and that's all because of this coach. I think sometimes during this season we saw unlucky things happen to Chelsea but I think Pochettino tried to his beat for the team.
For example, recently they got two new injured players, Robert Sánchez, and Trevoh Chalobah.
One goalkeeper and one defender injured in the team can make the team be weak in the next games. The sad thing is these players got injured in a bad time and this happened when Chelsea was getting ready for the games after players took some rest.
Now Pochettino should start using Thiago Silva or Badiashile in the defensive line.
Honestly when you look at the both names mentioned above, you'd see that this excuse is not good enough. Both players haven't been a good part of Chelsea's success this season so I see no reason how the absence of these players would affect them when they host Burnley at Stamford Bridge.
Chalobah hasn't featured well for Chelsea in defense this season ad could also be amongst names to be axed from the first team. In the case of Sanchez, he will never get back on into the first team because, that current goalie for Chelsea has done a much better job. So much confidence when you watch him play, all he needs right now is a stable defense to complement his efforts.
I double doubt you're a blue, coz if you're one, you'll not be saying all these.
One more thing to look at has to be the medical team of Chelsea. They also had same issues with Ngolo Kante. Injured for too long even during recovery process.
