William Saliba and Gabriel Jesus impressed, whilst recently selected England international Ivan Toney disappointed as Arsenal beat Brentford 0-3 on Sunday afternoon.
Saliba put the away side in front with a brilliant header which snuck in at the far post.
There was some dispute about whether the ball had crossed the line, but the referee, David Coote, had the decision verified by goal-line technology.
Arsenal's lead was doubled just before the half an hour mark.
Granit Xhaka found some space on the edge of the box and delivered a fantastic cross for Gabriel Jesus who headed past David Raya and into the Brentford net.
The home side were restricted in the first half and did not really trouble Aaron Ramsdale.
The Bees' troubles continued into the second period when Fabio Viera's long distance strike put Arsenal three to the good.
Mikel Arteta's side controlled the second half and limited the influence of the in-form Toney.
The Premier League welcomed its youngest ever player when 15 year old Ethan Nwaneri replaced Viera in the late stages of the encounter.
David Raya - 6/10
Had no chance with any of the goals. Made some crucial saves to keep the game at 3-0. His distribution was brilliant at times, creating chances out of nothing for the home side.
Rico Henry - 6/10
Allowed Saka some joy down his side. Made life tricky in some periods for Arsenal with his relentless pressing. Could have closed down Bukayo Saka for the third goal, allowed the Englishman to cut in and set up Viera.
Ben Mee - 5/10
Sloppy at times. Gave away four fouls and managed to escape without a booking. Was dragged down just outside the box which gave Brentford a free kick in a dangerous area.
Pontus Jansson - 4/10
At fault for the second goal. Lost a header to Gabriel Jesus, something a tall defender like the Swede should have been able to deal with. Did not pose any threat to the Brazilian when he went up for the header.
Kristoffer Ajer - 4/10
Looked shaky at the back and uncomfortable throughout. Was not at fault for the goals but did not look solid.
Aaron Hickey - 5/10
Minimised the effect of the Gunners' left-hand side. Gabriel Martinelli was kept out the game. Did not really have an attacking impact.
Josh Dasilva - 5/10
Struggled to make a difference. At times he managed to find some space but was ineffective.
Vitaly Janelt - 5/10
Similar to Dasilva. Was not able to get on the ball and was sloppy with his passes. A poor performance overall.
Mathias Jensen - 6/10
Was the best of the midfielders. Looked to create chances when he could. However, he was dribbled past with ease at some points.
Bryan Mbeumo - 4/10
Bullied by the Arsenal defence. Not much joy at all and careless on the ball. Gabriel and Saliba minimised his effectiveness.
Ivan Toney - 4/10
Found it difficult to get the freedom he has been able to have in the last few games. In Saliba's pocket. Took a free kick which sailed over the bar.
Frank Onyeka - 6/10
Did okay when he came on. Passing was on point and solidified the midfield to a degree.
Mikkel Damsgaard - 6/10
Had a half chance late on which was saved by Ramsdale. Good movement in the box and he created the chance for himself with great positioning. Had their first shot on target.
Shandon Baptiste - 6/10
Completed the trio of midfield substitutes. The new trio improved Brentford and created some chances.
Yoane Wissa - 5/10
Had a total of five touches. Did not change the game when he came on.

Arsenal
Aaron Ramsdale - 7/10
Kept a clean sheet and had nothing to worry about. Made the saves he needed to make and had a pretty simple game in the Arsenal goal.
Kieran Tierney - 7/10
Had a good performance. Attacking and defensively strong and put in a solid shift in the absence of Oleksandr Zinchenko.
Gabriel - 8/10
Really strong defensively. Aerially bullied the Brentford front line and, as a result, minimalised the home side's chances.
William Saliba - 8/10
Scored a great header which he flicked onto the far post and in. Defensively brilliant and another performance which would have impressed Mikel Arteta.
Ben White - 7/10
Took up the new position at right back with ease. Looked assured and was not troubled at the back. Very good from the Englishman following his omission from Gareth Southgate's squad.
Granit Xhaka - 8/10
One of his best performances of the season. Provided a cute ball for Jesus' bullet header. Passing was on point. Picked up a silly booking for stopping a quick break.
Thomas Partey - 8/10
Integral to the Gunners' midfield. Was very dominant in the middle of the park and skipped over challenges well. A crucial part of Arteta's plan, as seen today.
Bukayo Saka - 8/10
Found a lot of space down the right-hand side. Link up play and created openings. Became provider for the first and final Arsenal goals.
Fabio Viera - 7/10
Scored his first goal for Arsenal with a beautiful long-range strike that cannoned off the post. Looked promising when going forward. An exciting prospect.
Gabriel Martinelli - 6/10
Kept relatively quiet in the game. Majority of Arsenal's play went down the opposite side. Did not have the impact he would have hoped for.
Gabriel Jesus - 8/10
Looks a really good purchase from Arsenal. Scored his fourth goal of the season with a great header which gave Raya no chance. Gained a harsh yellow card for his first foul of the game
Sambi Lokonga - 6/10
Completed what was asked of him. The game fizzled out when he came on. Kept the ball well and continued Arsenal's dominant display.
Eddie Nketiah - 6/10
Made a few nice runs and nearly got on the end of a parry from Raya. Did not see much of the ball when he came on.
Takehiro Tomiyasu - 6/10
Brought on by Arteta in the final minutes. Kept out the side due to Ben White's excellence.
Marquinhos - 6/10
Not much to say about the Brazilian. Only played a minute of action.
Ethan Nwaneri - 6/10
A Premier League record holder. Became the youngest ever player at the age of 15.
Player of the Match - Granit Xhaka (8)
