Sorry Don, i have to disagree with only Zubi and Mosquera being the only ones making significant contributions. Eze and Gyokeres (as Panda said) have also made some. And Noni was filling in very admirably for Saka while he was out. Hincapie is only starting to get minutes now because he was injured, but he has looked very solid, and Norgaard is never gonna get huge minutes, but he's also contributed to us winning games (and so has Kepa, especially v. Brighton in the CC)
Its not about getting carried away with the number of players coming in. It's more the quality of those players, and the depth that its created. Even pundits that dont particularly like Arsenal have conceded that our transfer business this summer has been spectacular, and has made us into a deep, strong and well rounded team.
