Roger Federer admits he is "missing" his former coach Stefan Edberg but says he is "excited" about working alongside Ivan Ljubicic.
Ljubicic joined long-time mentor Severin Luthi on the team following the season-ending ATP World Tour Finals in London after Edberg left to spend more time at home.
The Swede enjoyed two years with Federer and made a big impact, reviving the veteran's attacking instincts by rushing the net on his opponent's second serve and helping him play some of his best tennis in 2014.
"Of course I miss him. It's normal. He was a great asset on the team. Nicest guy ever," Federer said.
"I have got used to Ivan now being on the team for the last sort of month or so. It's not that different anymore like it maybe was at the very beginning.
"But it was always very special of course looking up to the player box and seeing Stefan there. It always felt somewhat surreal to have him support me and be there for me. That's why I had a great time with him.
"It was his birthday yesterday. I congratulated him for that. Hopefully we can speak in the next few days and see how he's doing. We had a great time.
"Looking ahead, I'm excited with Ivan and Severin and the rest of the gang."
The 34-year-old Swiss, still the doyen of men's tennis, has been showing no sign of fading as he seeks a fifth title at Melbourne Park.
World No 3 Federer has been sublime so far, cruising through his first two rounds, and will take on the man once labelled 'Baby Federer' Grigor Dimitrov for a place in the last 16.
