Jorginho was promoted to vice-captain this season and has formed an impressive midfield partnership with Kovacic.
And the Croatia international says: "Sometimes when I don't see my player, he pushes me that I need to be there and pay attention. In this aspect Jorgi is great. He is really good at organisation.
"We try and communicate with each other and know where each other is.
"When I come a little bit deeper, Jorgi goes a little bit more up. In this position we change quite a lot and we like to do one-twos.
"I like to have the game in front of me, but sometimes I try to be on the same line as him, so with one pass I can break past him. That's why sometimes when we play as a two, we can play a forward pass to break the lines."
For his part, Jorginho says communication is key to the success of their combination.'
"You need to speak all the time," the Italian international told chelseafc.com.
"Communication is key because then you can help your team-mates by saying "turn" or "play one-touch", or to be aware of counter-attacks when we are attacking, talking to the full-backs or the other midfielder."
