Showed bravery early on in a 50/50 with Young and made a wonderful stop from Cleverley, but could do nothing about either of United's first two goals. Replaced at half-time through injury.
The former Manchester United trainee volleyed home emphatically to open the scoring but struggled with Rooney's movement, and headed in at the wrong end for United's third.
Rose well to set up Chester's early opener, and put in two superb challenges close to half-time to raise the noise levels at the KC. Hit the bar in the second half with a header as he dominated in the air. Booked late on.
The left-back looked uncomfortable up against Januzaj, picking up a caution as he tried to match the youngster's speed, which resulted in Smallings opener. He allowed Young in far too easily for United's third, and had a shocker in general.
The centre-back stood up well to the challenge of United and could have given the home side the lead again in the second half, but didn't connect well enough with a header.
Held his position well in the centre without really unlocking the United back line, but struggled as the game wore on.
Ahmed El Mohamady
Got down the right well to force a corner that led to Chester's opener, and drew a booking from Januzaj. A lively display full of energy.
The central midfielder was composed as usual on the ball but couldn't quite find his range with long passes.
The midfielder put himself about well in the opening stages and scored a fortuitous second for the Tigers. Tracked Valencia well down the wing, but was replaced at half-time.
The striker was quiet in the first half save for a deflected effort which went close five minutes from the interval. Worked hard up front though.
The forward held up the ball well in advanced positions to unsettle Evans and Smalling, and tested De Gea with a fierce drive early in the second half.
The Spaniard could do nothing about either Hull goal, with Evans deflecting the second past him. Came out for a ball that was never his late on and almost cost United, but made a superb stop to deny Chester late on.
The wing-back did not get off to the best of starts, and picked up a groin strain forcing him off for Januzaj early on.
Looked lost early on but rose well to head United's opener and restore the belief.
The centre-back had a nightmare early on, giving the ball away and deflecting Meyler's tame shot past De Gea. He was more composed in the second half, but cannot give goals away that cheaply any more.
The Frenchman struggled with El Mohamady's overlapping runs down the wing, forcing Cleverley and Januzaj into desperate tackles, and failed to get forward with his usual vigour.
Almost scored a peach from distance but was denied well by McGregor. Otherwise solid if unspectacular.
The midfielder was quiet on his first start for over a year but tidy in possession, and battled well whenever the chance arose. Looked understandably off the pace as the game wore on, and was replaced by Chicharito on the hour.
The winger put in a few teasing crosses from the left but couldn't work a shooting position to keep up his recent goalscoring form. Switched to the right and was far better, finding space past Figueroa to force Chester's own goal.
The Eduadorian was forced to right-back after Rafael's injury, but was disciplined defensively - save for his comical booking - and still got forward well to support Januzaj. Send off stupidly late on for booting the ball away.
The young forward supported the play well and linked with Rooney to set up United's second. A professional display from the striker, without ever looking truly dangerous.
The striker put in a great cross for Smalling to head home and then scored a stunning volley to level the game at 2-2, while his presence unnerved Chester for the defender's own goal. Whenever the going gets tough for United this season, Rooney stands up to be counted.
Came on for the injured McGregor at half-time. Could do nothing about Chester's own goal, but was off his line well to deny Chicharito.
Replaced the impressive Meyler at the interval but had little impact.
Replaced the disappointing Figueroa with 20 minutes to go.
Came on early for the injured Rafael and immediately made a difference, winning the set-piece for Smalling's goal and bamboozling Figueroa into a booking. Cautioned for a rash challenge.
The striker looked desperate to impress from the bench but wasted the ball on numerous occasions to the frustration of his team mates.
