But the United veteran expects improvement in the backline at Old Trafford.
“We are interchanging the defence too regularly at the moment because of injuries and it has caused us a problem,” Neville explained.
“We had to change our keeper for the opening two months of the season, then Rio Ferdinand and Nemanja Vidic have been injured.
“Before that it was Wes Brown. It means more changes than the manager would like. He wants a consistent back four, which is what we have had for two or three seasons.
“We definitely want to improve defensively and once we settle into our stride I am sure we will become better.”
“Things are not too bad here,” he added. “We are through to the quarter-finals of the Carling Cup, we are two points off the top of the league – which is probably the best start we have had in years – and we are through to the knock-out phase of the Champions League with two matches to spare.
“It is always the same at this club. When you lose a game at Liverpool there is criticism afterwards.
“But we have beaten Arsenal at home, we have beaten [Manchester] City at home. We have had other good results. We are not concerned by anything that happens externally.”
