What next for Arsenal's midfield?

Arsenal head into this international break with two wins and a draw and a solid start to the Premier League season, but there is still a feeling they could have done better. The red card for Declan Rice was a big factor against Brighton even though they had chances to win the game themselves with Kai Havertz and Bukayo Saka late on. Rice now misses the north London derby, which is a big blow.
