Speaking after the 3-1 win against Arsenal at Stamford Bridge on Friday, Hayes admitted she regretted her comments, although stopped short of taking them back.
"I let myself down yesterday," she said. "I didn't think it was right for me to use the term 'inappropriate' for the players. I don't take those things back but I have zero criticism of any player in my dressing room for anything. Their professionalism, for what they've given to the club regardless of their status, regardless of who they're in a relationship with.
"I've been unbelievably supportive of all of the players. I've been a champion for equality and for equity. As I keep saying to our players all the time, even if we have disagreements in life, we mustn't play them out publicly."
