John O'Shea claims Old Trafford's increased capacity can prove to be an important asset against visiting teams.
A club record home attendance of 75,453 watched United beat Tottenham on Saturday, and the Irish utility man says he and his team-mates have noticed a conspicuous improvement in the ground's atmosphere
O'Shea told MUTV: "It's fantastic to get crowds like this at Old Trafford. It is always a great atmosphere every game but we have all noticed an increase in volume.
"That can only benefit everyone at the club. This is where we want to be."
United currently top the Premiership with four straight wins and begin their Champions League campaign at home to Celtic on Wednesday night.
With Wayne Rooney and Paul Scholes back from suspension, plus Alan Smith, Gabriel Heinze and Nemanja Vidic all well down the road to recovery, O'Shea says the squad is buzzing.
"This is a positive time for the club with players coming back from injury and suspension. It is important we maintain this form and that is what the manager has re-iterated to us."
O'Shea was delighted that United followed last week's international break with three points against Spurs on Saturday, following last year's slump at the same stage.
"We had a similar start last year but slipped up after coming back from internationals," he said.
"This time it was different. It is always tricky especially when you are playing a good team like Spurs. You have to be on your guard.
"But we did enough to edge the win and get the three points, so we are ahead of ourselves compared to last year."
