When asked to describe Emma Hayes, Macario ended her answer with a simple statement: "Oh, you'll find out soon enough!"
Macario has been working under the future USNWT boss since arriving at Chelsea, which will only make this transition back to the national team even easier. Hayes has been the one managing Macario's recovery, helping her with the big and small steps that have allowed her to get back to full fitness.
Hayes is "quite the character" Macario says. She's loveable and fun and personable. She's also sat Macario down at times when she needed a more stern response.
"We've had a few hard conversations sometimes when perhaps I was not making the best decisions," Macario recalls. "She definitely has given me a lot of like tough love, which I really appreciate."
Hayes, meanwhile, has already begun to hear the jokes from Macario. The road to the Olympics is wide open... only Hayes can really stand in the midfielder's way.
“Cat is one of the most popular people in our dressing room, she’s so likeable, she’s so charming and charismatic," Hayes said of Macario recently. "She’s actually getting a little cheekier, I’ve noticed in the last few days, she had to fill out this form to be included in an Olympic roster and she said: ‘Now all you have to do is pick me!’ But Cat is someone who is not 100% yet, but she’s not far away from starting a game.”
On the other side of that, Hayes is going to be a hit with the U.S., Macario says, an outsider and an insider combined that can really change the program from the very top.
"She's quite the character, I'll say that!" Macario says with a laugh. "She's just a serial winner. I feel like she challenges us every single day and I do feel like she will make our national team even better. She does bring a different perspective coming from Europe, and she has been here in the US as well before so that's something nice that I think we can implement into our game.
"I feel like she just really takes care of the little things that come with winning and just dominating the game, not only just those two hours that we are on the pitch. I do feel like she focuses on so many things, honestly, things that I sometimes never even imagined. I feel like that's what makes her the best.
"She has an incredible personality that I'm sure you guys will love... You'll find out soon enough!"
The world will find out soon, too. The Hayes tenure is getting set to begin. The soon-to-be-ex-Chelsea boss arrives this summer to usher in a new era for the national team.
And there's a pretty good chance that Macario is one of the faces of that era. It'll take some time, but it begins this Saturday against Japan. After two years out, Macario is back and finally ready to become the USWNT star everyone knows she can be.
