Speaking on Adebayo Akinfenwa's Beast Mode On podcast, the striker surprisingly named former Swansea winger Mo Barrow as the toughest opponent he's ever faced.
The choice raised eyebrows, especially given Antonio's experience marking top talents like Eden Hazard and Marcus Rashford during his time as a defender.
"I've marked (Anthony) Martial, Hazard, Rashford. All these people," he said.
"The one who ripped me the most. He destroyed me. Mo Barrow. They won 3-0, all from him, through my legs, assist. I stood there like, 'oh sh*t'."
Antonio left West Ham when his contract expired in June, but the club has kept the door open for a possible return.
