Danielle Reyna -- the mother of USMNT player Gio Reyna -- is admitting she's the individual who notified U.S. Soccer about a 1991 domestic violence incident involving Gregg Berhalter.
As we previously reported, Berhalter claims someone outside the organization was attempting to get him fired by exposing an altercation from when he was an 18-year-old college freshman ... in which he kicked his now-wife, Rosalind, after an argument.
Gregg Berhalter Claims Someone Pressured USMNT To Fire Him Over 1991 Incident
Danielle -- who's married to ex-Team USA captain Claudio Reyna -- says she told U.S. Soccer about the incident because she was unhappy with how Berhalter spoke about her son following the World Cup.
Shortly after USA was eliminated, Berhalter said he was close to sending a player home for his actions on and off the field ... and although he never named Gio, it was clear who he was talking about.
Danielle released a statement on Wednesday ... saying, "I thought it was especially unfair that Gio, who had apologized for acting immaturely about his playing time, was still being dragged through the mud when Gregg had asked for and received forgiveness for doing something so much worse at the same age."
Danielle -- who played for the USWNT in 1993 -- also claims Berhalter is making his 1991 incident out to be less serious than it actually was.
"Without going into detail, the statements from yesterday significantly minimize the abuse on the night in question," she added. "Rosalind Berhalter was my roommate, teammate and best friend, and I supported her through the trauma that followed."
Danielle wasn't the only one pissed -- Claudio also released a statement to ESPN ... saying he spoke with U.S. Soccer officials about how Berhalter was handling his son, but denies making any sort of demands.
"While in Qatar, I shared my frustrations about my son's World Cup experience with a number of close friends, Earnie [Stewart] and Brian McBride among them. However, at no time did I ever threaten anyone, nor would I ever do so," Claudio said Wednesday.
FYI -- Gio barely played during the World Cup ... despite expectations he would play a big role in America's run.
U.S. Soccer is investigating the Berhalter incident ... as well as "potential inappropriate behavior towards multiple members of our staff by individuals outside of our organization."
While the probe continues, USMNT assistant Anthony Hudson will be in charge during a team camp later this month.
