Tbh those are all cosmetic changes. Arsenal biggest problem was depth and quality in attack. Saka was the only one good enough for a starter. Yes CF and LW but Gyokeres and Eze are on the way. Instant starters. Martinelli, Madueke, Havertz and Jesus would add depth. Midfield is well covered with Rice, Zubamendi, Merino, Norgaard and Odegaard. Timber, Saliba, Gabriel and Calafiori world class defense when healthy. Some talented academy players as well and Kepa is great number 2.
