Manchester United are in the Premier League bottom three following the 4-4 draw with Aston Villa, piling pressure onto Michael Carrick

Former Manchester United defenders Gary and Phil Neville have warned Michael Carrick that a back four featuring Leny Yoro and Ayden Heaven will result in the club suffering relegation at the end of the season. The side currently sits in the relegation zone, one point adrift of safety following a dramatic 4-4 draw with Aston Villa.

The Reds scored twice in stoppage time to save a point from the game, but it was not enough for them to climb out of the bottom three positions. It has led to more talk over Carrick's future as we enter the second international break of the season.

United's defensive frailties have been exposed this season. They have conceded more goals than any other team in Europe's five big leagues in all competitions.

It is well established that United have neglected to strengthen their defensive options in the last few transfer windows, having failed to make a significant signing in that area for more than two years — and Neville fears their current crop could drag them into the second tier.

He said on NBC Sports: "The reason Manchester United have conceded four goals is because they haven't invested in the defence in the transfer window. Everyone knew they had to do that; they needed defenders. The current ones are making mistake after mistake after mistake.

"The defenders that finished that game will get you relegated. Watch the defensive errors... we all screamed in the transfer window that they have to bring some defenders in. They had to bring the transfer budget forward and bring defenders in."

Bother Phil was in agreement, saying: "This team, I think Gary said it, [Noussair] Mazrouai, [Leny] Yoro, [Ayden] Heaven, [Patrick] Dorgu, finished the game.

"That back four gets you relegated. That back four gets you the sack as a manager. And that back four cannot keep Man United in the Premier League."

Gary then added: "It's rinse and repeat, isn't it? [Ruben] Amorim, [Erik] Ten Hag, Ole Gunnar Solskjaer, Carrick, Jose Mourinho, Louis van Gaal, David Moyes, Ralf Rangnick - some of them are world-class managers who have had success, there are a lot of promising young managers there, ex-players who know the club as well.

"None of it has worked, because if you recruit badly, if you've got poor performance department, poor recruitment department, you've not got leadership that is strong right through the spine of the football club, you will fail."

United opted to spend their entire £155million summer budget on midfield reinforcements, bringing in Youri Tielemans, Andrey Santos and Carlos Baleba. That strategy is already proving costly for the side, who have conceded 19 goals in their 10 Premier League outings.

Lisandro Martinez, who was absent from the matchday squad and was recruited by Ten Hag in 2022, has already publicly taken aim at the board for failing to adequately strengthen the squad. He singled out Jason Wilcox by name just weeks ago, criticising him for not bolstering the playing ranks.

The stalemate with Villa - whose manager Unai Emery was furious at his side's late capitulation - leaves United heading into the international break rooted in the relegation zone. Their 18th-place standing represents their worst position after 10 top-flight matches since 1986/87, when they sat 20th.
