Former Arsenal and Manchester United defender Mikael Silvestre says he always knew Cesc Fabregas was behind pizza-gate.
Sir Alex Ferguson was hit by flying food as his players clashed with their Arsenal rivals in the Old Trafford tunnel following the 2-0 United win in October 2004.
The match halted Arsenal's unbeaten run in the Premier League at 49 matches and marked a high water mark of acrimony in the intense rivalry between the two clubs.
Speaking to The Athletic's Talks of the Devils podcast, Silvestre said: "There was flying pizza on Sir Alex's suit so it was a crazy end.
"I had heard from the French guys in the national team, so I knew it was Cesc.
"So when I joined the Arsenal team, I said 'I know it was you, don't lie to me!' He was laughing about it.
"But at the time, I can tell you, Sir Alex was not laughing and we were made as well.
"It was a foolish moment from Cesc but you must remember he was 18 at the time, an 18-year-old throwing pizza!"
