He completed 93% of his passes and also attempted to initiate attacks from the back with seven long balls.Sead Kolasinac - 7/10Arteta bamboozled the fans by starting the Bosnian, who's set to leave the club soon. Although he was deployed in the centre-back role, Kolasinac was seen mostly near the left-fank and turned in a decent shift. He completed 95% of his passes but got ahead of his own skies at times, getting himself booked in the second-half.Nuno Tavares - 6/10Of all the left-back options for Arsenal, it was Tavares who started there in another perplexing move and the youngster didn't have a good outing. He misplaced a lot of passes, got dispossessed a staggering 24 times, and was poor in his ground and aerial duels too.Mohamed Elneny - 6.5/10The Egyptian went about his business as usual. He sprayed passes all across the pitch and created one big chance. But nothing spectacular to see from him.Granit Xhaka - 7/10Xhaka's work-rate was commendable as he ran his socks off. He completed 93% of his passes, was strong on the ball, and made five long balls too. Yet, the Swiss international was taken off after only 67 minutes.Nicolas Pepe - 9/10A huge menace down the right flank. His effort in the first-half came off the upright but Aubameyang was on hand to turn in the rebound but got his goal just a minute later. Then in the second-half, another strike of his ricocheted off the bar before assisting Lacazette. An eventful night.Nicolas Pépé vs West Brom:1 goal2 assists1 pre-assist3 chances created2 key passes2/2 accurate long balls89% pass completionQuality playmaking performance from a guy that lacks fundamentals pic.twitter.com/jbPUm0f9gt— ⓢ (@somtozil) August 25, 2021Martin Odegaard - 7.5/10He drifted in and out of the game but did enough to register an assist, putting things on the plate for Saka early on in the second-half. He had an 85% pass completion rate too. Not bad for a second debut for Arsenal.Bukayo Saka - 9/10Aubameyang took home the man of the match award but Saka was equally impressive for Arsenal on the night. He was the architect of the rout - distributing the ball excellently, linking up with fellow attackers to devastating effect, and even getting on the scoresheet. Talismanic.Bukayo Saka nets his first goal of the season and he's loving it 🤩 pic.twitter.com/g9aGjK4Or5— International Champions Cup (@IntChampionsCup) August 25, 2021Pierre-Emerick Aubameyang - 10/10Hat-trick hero of the night, Aubameyang didn't produce a vintage performance, but gave a poaching masterclass in the first-half, firing a rebound twice before capping off his treble with a peach of a strike.
