British number one Johanna Konta says she has "grown as a player" since losing to Karolina Pliskova in May, as she prepares to face the Czech third seed in the US Open last 16 on Sunday.
The 27-year-old beat Konta in straight sets in the Italian Open final.
Konta, 28, has since reached the French Open semi-finals and made the last eight at Wimbledon, and has looked in good form so far at Flushing Meadows.
"I am looking forward to seeing how I can do a bit better," Konta said.
The world number 16, who beat Chinese 33rd seed Zhang Shuai 6-2 6-3 in the last round, says she hopes to "ask some better questions this time around" against Pliskova.
