Roger Federer says he is happy that he "does not feel like an alien" in his return to tournaments as he acknowledged that certain questions can irk a retired player and make him never come back.

"I think I'm decent at doubles, but I'm not quite as skilled as I am in singles. I look forward to seeing him tomorrow in singles. I hope he enjoyed the doubles match; it was great to see him during practice.

Roger Federer retired two years ago but his connection to tennis remains stronger than ever. The return of the Laver Cup is another reminder that he never left the stage.
