Phillips started alongside Kabak for the first time in the win at Sheffield United.
He told liverpoolfc.com: "I feel like we worked well together. Obviously when it's a new partnership you are sort of learning on the job how the other one might play.
"We've trained together so I already had an idea before the game, it wasn't like it was completely new, and I've seen him play so I had an idea of how he played [and] he had an idea of how I played.
"But certainly when you're playing alongside each other in that moment then you get a better idea and I think it's always good to build relationships on the pitch with whoever you are playing with, certainly as a centre-back pairing. It'd be good to get the opportunity to do that and try to progress together."
Phillips admits tonight's clash with Chelsea will be a test.
He said, "Yeah, it will be. But every game in the Premier League is a big test and we've got to go into it the same that we go into all of our games, with the aim to put in a good performance and win and, hopefully for the defence, a clean sheet. Like I said after the Sheffield game: build on that, continue to take our chances. But it will be a big test."
