Paul Scholes criticised Manchester United's "sloppy" display after their 3-1 loss away to Watford on Sunday.
Goals from Etienne Capoue, Juan Zuniga and Troy Deeney, with a late penalty, saw the Hornets to a comfortable win at Vicarage Road as United, whose lone goal came from teenage striker Marcus Rashford, suffered a third straight defeat under manager Jose Mourinho.
Former United midfielder Scholes, now a television analyst with BT Sport, didn't spare his old side.
"The quality on the ball was as poor as you've seen from a Man United team, and that's just the way it is at the minute," Scholes said. "You're not sure what you're going to get.
"Rashford is probably the only shining light really and he didn't have his best game today, but he looked a threat. I just think in possession Man United were really, really poor.
