Paul Scholes has hit out at inconsistent Manchester United and claims: "You don't know what you are going to get!"
The Old Trafford legend watched on as Watford secured a dominant 3-1 win over United to hand Jose Mourinho's men three consecutive defeats.
Marcus Rashford had cancelled out Etienne Capoue's opener, but Juan Zuniga and Troy Deeney netted in the final 10 minutes to secure the Hornets' first victory over United for 30 years.
Scholes, working on the BT Sport punditry panel, claims that despite the big names on the pitch for United, they are not performing.
"The quality on the ball is as poor as you will ever see from a Manchester United team," he said. "But that's the way it is at the moment.
"You are not sure what you are going to get!
"Rashford is the only shining light really and he didn't have his best game. He looked a threat but in possession, United looked really, really poor.
"I think individually they were not good enough. In possession they were sloppy and giving the ball away all the time."
One of the faults that Scholes picked out was the role of Marouane Fellaini in the centre of midfield.
He started in a three alongside Paul Pogba and Wayne Rooney, before Mourinho reverted it to a two in the second half, with Rooney further advanced.
But Scholes believes that the Belgian does not have the quality to play in the role he has been deployed.
"I thought Fellaini was alright today; he does a job in there," said Scholes.
"But I think that if you are Manchester United, you need more than that.
"You need someone who can stop the play as well, someone who can stop the opposition but who is capable of controlling a game of football as well, playing forward and passing forward.
"I can't understand why Michael Carrick is here. He looked like he was leaving last year and he's not been involved for a minute this season.
"What he has done, I don't know.
"Schweinsteiger he is not keen on either.
"I just think that they need to get a playmaker in there.
"At the end of the day, you are Manchester Unite d and you are coming to Watford. You're not going to Arsenal!"
United will look to avenge the poor run when they travel to Northampton in the EFL Cup on Wednesday night.
