Player Ratings: Manchester United 8-2 Arsenal

Another mixed afternoon for the young Spaniard. Excellent first-half penalty save appeared to improve his confidence but let Walcott's tame effort through his body on the stroke of half-time.

Some classy moments at the back from the defender but he switched off mentally on too many occasions, not least when he tugged back Walcott to conceded the penalty.

Another mature performance from the summer signing that belied his age. Superb anticipation to read Arsenal attacks and won everything in the air.

The Frenchman was solid defensively against Walcott and provided an excellent attacking outlet in support of Young.

The England under-21 international is quickly developing as a right-back and was once again very impressive. His defending was strong and he joined United attacks with tremendous power and pace.

Came into the game full of confidence and controlled play in central midfield with his energy, skill and passes. The Brazilian's swagger was summed up by the glorious chipped pass to Welbeck to create the opener.

Another of the United young guns who continued his good form. Played some lovely one and two-touch passes but sat a little deep in the first 20 minutes of the second-half. Missed great chance to score when he shot straight at Szczesny when through on goal.

The England winger has looked a very astute signing for United and he showed why again with a magnificent curling effort from 25 yards to put the hosts 2-0 up. Pace and delivery were too much for the Arsenal defence and he added his second with another curler in the dying moment.

Trickery and dribbling ability caused Arsenal problems but the final ball was missing - until he produced an audacious dink over Szczesny in the 67th minute to score United's fifth of the afternoon. Immediately substituted and replaced by Park.

Scored his second goal in a week as he shrugged off Djourou and nodded the ball over Szczesny to open the scoring. Showed some neat link-up play but his afternoon was brought to an end by a hamstring injury 10 minutes before half-time.

The Pole could do little as the United goals rained in and it could have been more had he not made some sharp stops to deny Young and Cleverley.

Made some good interceptions in the opening exchanges but could not handle United's attacking movement as Arsenal crumbled.

Out-muscled by Welbeck for the opener and the afternoon only got worse for the Swiss defender as he allowed United attackers the time and space to create - and convert - clear opportunities.

Too easily beaten by a drop of Nani's shoulder but wasn't helped by the fact he often found himself in two-against-one situations. Made some strong attacking runs in the first-half.

Arsenal's best midfield player of the afternoon - not that it means much. Completely overrun in the second-half but his composure and creativity on the ball was evident.

Should have been sent-off for fouls on Jones and Young that could have been straight red cards in their own right. Occasionally threatened and took a few pot shots at goal but the Russian seems to encapsulate the lack of winning mentality within the Gunners squad at the moment.

The Czech schemer was virtually anonymous throughout the game. Offered no defensive protection for the defence and didn't seem to want the ball.

The young midfielder was handed his Premier League debut and even he could not have imagined it would be this hard. Struggled to have an influence on the game and allowed United to operate too easily between Arsenal's defence and midfield.

Could never get into the game as Arsenal failed to give him the service to isolate Evra. Scored from a tight angle on the stroke of half-time but conceded a second-half penalty for a push on Evra.

Slammed Arsenal's second goal into the roof of the net from close range but it was only his second effort of note. The Arsenal captain was isolated on his own up front and was bullied off the ball when he did gain possession. Saw his tame penalty saved in the first half when United were just a goal ahead.
