The dominance of Serena Williams has led to the women's game often appearing somewhat one-sided over the last 10 years but Kerber's wins at the Australian and US Opens have seen her overtake Williams as the game's number one.

Before her breakthrough, Kerber was among a group of players to often fell short when it mattered, usually against the American.

Radwanska herself is one of those still looking to make her breakthrough but says the German has shown her and her contemporaries that they can develop the consistency required to win Grand Slams and reach the top of the rankings.

"Angie is playing unbelievable tennis this year," she told the Straits Times. "She showed that she can play great tennis on every surface, winning titles on clay, two Slams on hard courts, and making the Wimbledon final.

"She is the only player that played that well with such consistency over the whole season.

"Angie becoming No. 1 definitely sends a message to the locker room that we all have a real chance to win a Slam or get to No. 1, no matter our age or our rank."
