Chelsea and Germany goalkeeper Ann-Katrin Berger has revealed she has been diagnosed with thyroid cancer for a second time and will begin treatment this week.

Berger was initially diagnosed in November 2017 during her time with Birmingham City, but made a full recovery and was subsequently named in the PFA Team of the Year.

However, the 31-year-old said on Tuesday that after four years being cancer-free, a recurrence has been detected in her thyroid.

"I've said before that as a sportsperson, you have to fight every day to be the best you can be and that's something I will continue to do," she said in a statement.

"I hope by sharing my journey I can help others that find themselves in a similar situation.

"I am working closely with my club doctor and specialist in London, and my treatment will start this week.

"I remain positive that my treatment will be as effective as last time, and I'm looking forward to returning to the pitch and seeing you all at Kingsmeadow and Stamford Bridge."

Berger has played a key role between the sticks for Chelsea in their Women's Super League triumphs of the past three seasons.

The former Paris Saint-Germain goalkeeper, who won the WSL's golden glove in 2020-21, was also part of the Germany squad that reached the Euro 2022 final last month.
