Chelsea defender Maria Thorisdottir has signed a new two-year contract with the Women's Super League club until 2021.

The Norway international, whose existing deal had been set to expire this summer, helped the Blues win a league and FA Cup double last term.

She is recovering from a concussion injury suffered earlier this season but is nearing a return to full fitness.

Defending champions Chelsea are third in the top flight, six points behind leaders Manchester City.
