Izzy Christiansen

On 27 December 2019, Christiansen announced her return to England, signing an 18-month deal with Everton.

In March 2019, Christiansen underwent surgery on an ankle injury sustained in England's 3–0 SheBelieves Cup win over Japan. England coach Phil Neville called her "vital" to his squad and hoped that her rehabilitation programme would restore her to fitness for the 2019 FIFA Women's World Cup.

On 23 July 2018, Christiansen signed a contract with defending European Champions Olympique Lyon until 2020. In her first season with the club, Lyon won the treble: winning Division 1 Féminine, Coupe de France and Champions League.

Coach Mark Sampson gave Christiansen her senior international debut in a UEFA Women's Euro 2017 qualifying match against Estonia on 21 September 2015. She marked the occasion by scoring in England's 8–0 win.

On 7 February 2014, Christiansen officially signed for new WSL club Manchester City Women. On 16 October 2014, she scored the only goal to help Manchester City defeat Arsenal Ladies and win the 2014 FA WSL Continental Cup. In April 2016, she won three awards, two of which were the PFA Women's Players' Player of the Year and PFA WSL Team of the Year. Upon winning the awards, Christiansen said: "I'm pretty shocked. Three awards is a great achievement and I'm so pleased to have been able to have done that for the team."

Christiansen helped Great Britain to win a gold medal in the 2013 Summer Universiade in Kazan, Russia. In January 2014, she was promoted from the under-23s into the senior England squad, to replace Jodie Taylor who had withdrawn.

As a junior international, she won the 2009 U-19 European Championship and a silver in the following year's edition, and played the 2008 U-17 and 2010 U-20 World Cups.
