Arteta does not have a back up for Saka. No back up for Saliba. That Arsenal team still needs 4 top top players that can make the team better and easy to rotate. A striker, a midfielder, a centre back and one solid winger. Not average players. I also believe that Emile Smith Rowe shld be allowed to rotate with the 3rd person in the midfield besides Ødegaard and Declan Rice. He can play the left sided 8. Haverts would get better.
