Chelsea striker Sam Kerr is set to make her return from injury against Manchester City on Sunday in the Women's Super League.
The Australian forward missed Chelsea's 2-1 victory over Tottenham on the opening day of the season due to a calf injury that has troubled her since the Women's World Cup.
"She's back in full training," said Hayes at her pre-match press conference. "For Sam, she's never perfect, she always wants a little bit more, but she's available for selection."
Fran Kirby made her first appearance for Chelsea since February when she came on as a second-half substitute against Tottenham, but Hayes wouldn't reveal if the forward was fit enough to start on Sunday.
