Arsenal legend Thierry Henry says Manchester United have lost their fear factor since the arrival of new boss David Moyes.
Henry admits that in his time with Arsenal, a match with United - under the guidance of Sir Alex Ferguson - at Old Trafford invariably meant a long journey home without so much as a point.
United are currently languishing in ninth place in the Premier League, 13 points behind Arsenal and they have lost their last two games at home to Everton and Newcastle.
And Henry says that unless United recreate their fearsome reputation at Old Trafford, they are unlikely to be in the title-running come May.
"When we went to Manchester United, I can say it now, we knew they were going to come out strong," said Henry, who was in the Sky studios to provide analysis on the Champions League.
"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."
Arsenal are currently five points clear at the top of the Premier League and Henry admits he would love to have played with their record signing Mesut Ozil.
The Germany midfielder has played a big part in their rise to the top of the table since his arrival from Real Madrid and Henry 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."
