Chelsea boss Maurizio Sarri has expanded on why he feels Mateo Kovacic could cover Jorginho when required.
Sarri rates the Croatian ahead of N'Golo Kante as a midfield 'pivot'.
After victory over Huddersfield, he said: "Jorginho played very well and I put Kovacic on the pitch after the fourth goal because Jorginho had a little problem to his groin.
"This is the only reason, because in my opinion he played a very good match.
"We are trying during the training with two players – the first is Ampadu and the second is Kovacic. Maybe for the characteristics, Kovacic is more suitable for this team. As you know, Ampadu is more defensive, but Kovacic is really close to Jorginho at moving the ball very fast at one touch. So, I think in the future he will be able to do this position well.
"Kovacic could be a very good option, but then we need to recover completely Ruben Loftus-Cheek after the back problem. Then we can play sometimes with Kovacic as a central midfielder and Jorginho will be able to rest."
