SYDNEY, Aug 10 (Reuters) - The Women's World Cup has not seen the best of England, who must play better in their quarter-final clash with Colombia on Saturday, said defender Lucy Bronze. The fourth-ranked Lionesses survived a scare in Monday's round-of-16 penalty shootout win over a Nigerian side who gave England fits all night. "There's no point in playing our best performances in the first games, we might as well save them for the quarter-finals or further than that." England are among the favourites to win the tournament after the elimination of two-time defending champions United States, Olympic champions Canada, Germany and Brazil. Coach Sarina Wiegman said after the Nigeria win she had never experienced so many problems in a game or tournament.
