Arsenal's all-time top scorer Thierry Henry says Manchester United no longer scare opponents since the arrival of David Moyes.
Moyes became manager of the Old Trafford outfit in the summer following the retirement of Sir Alex Ferguson but has since gone on to struggle, losing five games in the Premier League including three at home.
Henry, who scored 228 goals for Arsenal in 377 games, admits he always feared the thought of facing Ferguson's United at Old Trafford but says he doesn't see that same factor in the current United squad.
With United languishing in ninth place, 13 points behind leaders Arsenal, Henry says the Red Devils must reinstall that fear factor if they are to climb the table.
"When we went to Manchester United, I can say it now, we knew they were going to come out strong," said Henry on Sky Sports.
"But now when I see teams going to Old Trafford, they are not even scared. They play. Some teams didn't even pass the halfway line. But when I see teams now, they are comfortable - they pass the ball around.
"They need to recreate the fear they used to have. Then they will be all right."
Henry also took the opportunity to praise new signing Mesut Ozil, saying he would have loved to play with the midfielder.
He said: "I would have loved to have played with him. He reminds me in a different way of Robert Pires.
"He seems like he always has time and we all know that's not the case. He plays like he's playing at home in his garden and nobody is watching."
