Harry Maguire has admitted that Manchester United's record at defending set-pieces isn't 'good enough'.
United appointed Eric Ramsay this summer as the club's first set-piece specialist and individual development coach.
It seems that United have actually gone backwards at defending set-piece scenarios since that appointment, though, and they conceded from yet another corner against Atalanta, albeit that goal didn't prevent them from completing a sensational comeback.
Leicester and Atalanta have scored corners against United in consecutive games and Maguire admitted that is not good enough.
Manchester United enjoyed a sensational transfer window, securing the signing of Cristiano Ronaldo, but Ole Gunnar Solskjaer is now under pressure to deliver silverware after a patchy start to the season. United face some big games after the international break.

â€œWe conceded two bad goals [against Atalanta]. Weâ€™ve got to sharpen up on that," Maguire told BT Sport.
"We didnâ€™t give them many chances throughout the game and weâ€™ve conceded two goals and found ourselves 2-0, but I think Marcus had two one-on-ones in the first half, so I knew when he got that third one there would be no mistake and it was a great finish.
â€œThatâ€™s not good enough [one clean sheet]. Thatâ€™s not good enough for this club. Weâ€™re working hard, working hard on the formula to be a lot more solid, but like I say, itâ€™s about winning football matches.
"I think the last three or four games, weâ€™ve conceded far too many goals from set-pieces. I think thatâ€™s four goals in the last four games now, so thatâ€™s something that we need to sharpen up on.
"At the start of the season, we were really good at defending those."
