How did match-winner Saka do at Villa Park?

Zion Suzuki: A debut for the £30m goalkeeper from Parma who had no chance with the opening goal. He misjudged his first corner but his distribution caught the eye and will be useful this season. 7Matty Cash: His usual solid display and got the better of Christos Tzolis, who was replaced at the break. 6Pau Torres: Helped keep Arsenal at bay until they broke the deadlock in the second half. 6Victor Lindelof: The Sweden international diligently tried to keep Arsenal in check. Has not let Villa down since arriving on a free transfer. 6Ian Maatsen: With new signing Matteo Ruggeri on the bench, he has competition and had his hands full with Bukayo Saka, and was beaten to the ball for the goal. 6Boubacar Kamara: The midfielder is so crucial to how Villa play and he offered an important shield to frustrate the Gunners until Saka's opener. 7Ross Barkley: The former Everton youngster has been given a second chance at Villa as they rebuild and tried to keep the hosts flowing. 6 John McGinn: The skipper drilled over and was his usual energetic self as Villa tried to unsettle Arsenal and did not drop his energy levels. 6Emi Buendia: The Argentina international hit the bar early and was a good creative outlet for the hosts but could not find the killer touch. 6George Hemmings: Villa rate the 19-year-old highly and he showed no fear against the champions. He threatened in the first half, especially with one low cross. 7Nicolas Jackson: The £65m record signing will take time as he replaces Ollie Watkins but showed flashes of what he can bring. 6Subs:Tammy Abraham (on 71, Jackson): Included despite Ipswich trying to take him on loan, but could not find a leveller. 6Alysson (on 71, Hemmings): The winger looked lively in his second-half cameo. 6Alejandro Garnacho (on 78, Barkley): 5Aaron Wan-Bissaka (on 78, Cash): 5Subs not used: Bizot, Bogarde, Lynch, Mings, RuggeriDavid Raya: A reliable display from Raya. A good range of passing. 6Ben White: He didn't produce his usual overlapping runs as much but helped the Arsenal back four keep a clean sheet. 6 Cristhian Mosquera: The 22-year-old produced a solid performance next to the more experienced Gabriel. Had to come off with an injury in the second half. 6 Gabriel Magalhaes: A chance early on from an Arsenal corner which he headed over. The Brazilian led the Arsenal back four as they picked up three points. 7 Riccardo Calafiori: Picked up his usual adventurous positions when Arsenal were going forward and provided the assist for Saka's goal. 8Declan Rice: Assured in the middle of the pitch and covered a lot of ground. Some important interceptions and threatening set-pieces too. 6 Myles Lewis-Skelly: Continued his excellent start-of-season form. Comfortable when under pressure and played with a lot of responsibility. 7 Martin Odegaard: A couple of nice passes in the first half but not enough impact going forward. Went close with a free kick in the second half. 6 Bukayo Saka: The winger scored the vital goal for Arsenal. The Gunners were not at their best going forward but most of the good moments involved Saka. 8 Christos Tzolis: A disappointing night for the winger who worked hard but lacked quality when going forward. Taken off at half time. 4Kai Havertz: It was a quieter night for Havertz but the forward still provided a focal point and held the ball up. 6 SubsEberechi Eze (on 46, Tzolis): Introduced at half time and played a big part in Saka's goal. 7 Merino (on 71, Odegaard): Added bite into the Arsenal midfield. 6Bruno Guimaraes (on 71, Lewis-Skelly): Came on for his Premier League debut. 6Ezri Konsa (on 78, Mosquera): Made his first appearance for his new club. 6 Martin Zubimendi (on 85, Rice): Came on for Rice as Arsenal looked to see out the game. 5Subs not used: Kepa, Hincapie, Gyokeres, Madueke.
