"Obviously he can take that to the grave, beating Roger Federer on Centre Court at Wimbledon," Matosevic said after upsetting Italian third seed Andreas Seppi 6-3, 6-4 yesterday.
"He'll take that. That's one of the greatest accomplishments you can have in this sport.
"But I'm feeling confident. I beat him the last time we played."
Ranked 56th in the world, Matosevic feels a much better player than that after claiming a series of top-20 scalps in 2013.
"My highest ranking is 39. I definitely think I can go higher," he said.
Focused only on Stakhovsky, Matosevic is refusing to let his mind wander to a potential semifinal showdown with Tomic in Sydney.
"I don't really look forward," he said. "I've done that before. Every tennis player has looked ahead and then you lose."
