Manchester United have hit back at Real Madrid after the Spanish club's president Florentino Perez described their conduct in the David de Gea deal as a "disgrace".
Perez also claimed that United's negotiating team "lacked experience" after the £29.5m deal for De Gea to join Real sensationally broke down at the last minute.
United have been accused of sending the paperwork for the deal too late and missing the August 31 deadline, but they insist they submitted all their paperwork by the midnight cut-off.
In a statement released on Friday, United said: "The facts speak for themselves and the FA are prepared to back our case that the documents were in on time.
"Real seem intent to move the focus away from their own clumsiness this summer. We all like to blame others but if you let one slip through your fingers into the back of the net, then ultimately the culpability is yours."
Meanwhile, De Gea has missed United's first six games of the season as a result of the ongoing saga, though he is now in line to return after the international break.
