Claudius -- I think they and Liverpool have also demonstrated the value of depth and competition. We often hear that it's all about the starting XI, but I look enviably at Liverpool who have 4 starters (Salah, Diaz, Gakpo, and Nunez) for 3 forward positions and 4 starters (Gravenberch, Jones, McAllister, Szboz) for 3 midfield positions.
We have unhealthy competition in contrast. It's a race to the bottom between Trossard and Martinelli, and Jesus and Sterling.
Arteta needs to look at what Curtis Jones is doing for Liverpool and fast track Nwaneri for a similar impact/role.
