Federer, who helped Team Europe claim three Laver Cup titles by beating Team World, will be present at this year's edition in Vancouver where a celebration is planned on Friday to mark the first anniversary of his final competitive match.
The 42-year-old had played alongside his great rival Rafa Nadal in that clash, losing to Jack Sock and Frances Tiafoe as Team World went on to capture the title.
"There's something in me that's Team Europe," Federer said.
"I'm happy if World wins, don't get me wrong, but somehow I can feel it deep inside, I want Europe to win.
"I like being in the tennis sphere," he added. "Maybe one day I'll be the captain of the team," the 20-times Grand Slam champion said. There's no plans as of now, but I think that could be quite nice."
