Hayes also outlined the importance of the return of Rose Lavelle, who hasn't appeared for the team in more than six months after undergoing ankle surgery.
"We're incredibly excited to have her back with us for multiple reasons," Hayes said. "First of all, her personality and the character in the locker room has been sorely missed the past six months. She's supremely gifted as a football player, and playing between the eight and 10 positions. She's someone who, I think, she's maturing a top level footballer.
"It's where her game has been going in the last 12 months she's she's starting to add new dimensions in between the lines. And I'm so excited for her that she gets back to be back with the team, but also we get to be back with the team when we go to Cincinnati, her hometown - and I know she's extremely excited for that."
