Steven Bergwijn ghosted past Maguire on the counter-attack before drilling a shot through the palms of Maguire to give Jose Mourinho’s side the lead at the Tottenham Hotspur Stadium.
The mistake prompted Keane to begin a frothing rant at half-time, where he claimed he would have “thrown punches” in the dressing room.
Read Keane’s rant in full:
“I’m shocked. I’ve seen a lot of football over the years, but to give away that goal, I’m fuming watching this game of football,” he said. “I can’t believe Man United, I can’t believe [Luke] Shaw heading the ball up in the air and running forwards.
“I am staggered at Maguire, staggered at how an international player can get done like this. And the goalkeeper, I’m sick to death of this goalkeeper, I’d be fighting him at half-time, there’s no getting away from that, I would be swinging punches at that guy. This is a standard save for an established international goalkeeper. I am flabbergasted. There’s got to be some stuff going on at half-time.
“Maguire, and De Gea, I wouldn’t let them on the bus after the match. These are established international players and we’re all sitting here, I know we’re here to analyse the game, we can analyse it till the cows come home. You do your job, we’re on about just getting in the top four, God forbid winning trophies. Shocking. I’m disgusted by it. De Gea, Maguire, hang your heads in shame.”
