Manchester United's back-up goalkeeper Altay Bayindir was blasted by Roy Keane for a 'basic' mistake to gift Newcastle their fourth goal on Sunday.
Ruben Amorim dropped Andre Onana after his error-strewn display against Lyon in the Europa League on Thursday night, handing Bayindir his first Premier League start.
But the decision backfired as Bayindir conceded four goals from six shots on target and gave away a cheap final goal in the 4-1 thrashing.
In fairness to the Turkish stopper, this was just his eighth appearance in almost two seasons at Manchester United.
But his decision to try and chip a ball through midfield, which Joelinton intercepted to set up Bruno Guimaraes, left Keane and Les Ferdinand questioning his 'common sense'.
'Of course (he was at fault). You go back to the decision-making. I'm not even sure what the big benefit (would be, making that pass). It's too risky,' Keane said on Sky Sports.
'It's absolutely too risky. There's players around you. At the highest level, it's about your decision making.
'I'm quick to defend goalkeepers when they first come into the team because I think it does take five, six, seven games to get up to speed with the shot. But that basic mistake there, I can't understand it.
'This is big boy stuff. You're up at Newcastle, Newcastle are flying, you do your own homework on who they're playing and when they're pressing you.
'If you're going to go long, make sure you go too far, so then at least it's up the pitch.
'But if you lose it there, someone is through on goal on top of you. That's just common sense.'
Ferdinand added: 'It's typical of what we're watching with goalkeepers noawadays being too precise, too clever.
'Just put your foot through that, say, "we're 3-1 down, let's not go 4-1 down by making a silly mistake." He doesn't, he tries to clip a little dinky ball into the centre-forward.'
'I'm just thinking: "what are you doing?"'
