Katarina Johnson-Thompson warned Nafi Thiam she is ready to challenge her for more titles after claiming heptathlon silver at the European Championships.
The 25-year old's second place sparked a medal rush for Great Britain in Berlin yesterday with Matt Hudson-Smith taking gold in the 400m and Meghan Beesley bronze in the 400m hurdles.
Jake Wightman also claimed bronze in the 1,500m.
Johnson-Thompson was just 57 points behind heptathlon champion Thiam, with the Belgian adding the crown to her world and Olympic titles.
Johnson-Thompson, who won the World Indoor pentathlon title and the Commonwealth Games heptathlon earlier this year, recorded a personal best of 6,759 points and believes she can close the gap on Thiam.
She said: "I feel like I can do it. I believe in myself and this is going to be good for me moving forwards.
"Up until this point, these championships, I wasn't as confident as I am coming out of them. Obviously I had tougher opposition here.
"I was happy with my first two medals but this has a big significance factor for me, especially given my build-up after the Commonwealth Games."
A calf injury affected Johnson-Thompson's European preparations, and she added: "It has taken a lot of work from a lot of different people to get me on the starting line.
"With my preparation and build-up, this has been one of my best performances ever."
Hudson-Smith said of his gold: "It's a good feeling. It was about winning."
