Former Manchester United defender Darren Fletcher has torn into Victor Lindelof for his defending during the first half of their Carabao Cup match with Manchester City.
Ole Gunnar Solskjaer's side trailed their rivals 3-0 at half-time, in the first leg of the Carabao Cup semi-final.
Goals from Bernardo Silva, Riyad Mahrez and an own goal from Andreas Pereira put Pep Guardiola's side in cruise control at Old Trafford before the break.
For City's second, scored by Mahrez after breaking the United offside track and rounding De Gea, Fletcher criticised Lindelof for a lack of defensive awareness to read the danger after his initial error, after heading the ball straight Silva.
"This is poor defending from Victor Lindelof. First and foremost, you're not playing against a Premier League striker, that is Riyad Mahrez," he told Sky Sports at half-time.
"Not only is it not a good enough header but his reaction, to just amble back, he makes an effort to slide but it probably doesn't help de Gea.
"This isn't good enough, he has to move Mahrez out of the way there. That's fine, it's a bad header, but what is your recovery like? That's ambling back, that's jogging back and they have been punished.
"If you defend like that against Manchester City you've got no chance. The third goal, it's a great counter-attack, but there are two or three defensive mistakes from Manchester United. If you do that against Manchester City, you get punished."
