Fara Williams has joined Arsenal Ladies from Liverpool.
The 31-year-old midfielder, who with 148 caps is England's record appearance holder, wrote on Twitter that she had signed for "the next two years".
The transfer comes shortly after she was awarded an MBE in the New Year Honours list, largely for being central to England finishing third at the 2015 World Cup.
"Fara is a great competitor and a fantastic character, too", Arsenal manager Pedro Martinez Losa told the club's official website.
"She is a player with huge experience at club and international level, and her reading and understanding of games is fantastic."
Williams won the FA Women's Super League with Liverpool in 2013 and 2014, and has previously played for Chelsea, Charlton and Everton.
