Can I just start by saying I do think you are better, you are a more settled & experienced team, I just don't think there's a massive gap between the first XI's that the league tables suggest, although we are exactly where we deserve to be.
As for our starting XI, i would pick something like this, but there's debatable positions, such as Auba / Laca or Smith-Rowe / Pepe / Martinell..
--------------------------Leno-----------------------
Bellerin-------Luiz--------Gabriel-------Tierney
------------------Partey------Xhaka-------------
----Saka-----------Odegaard----------Smith-Rowe
---------------------Aubameyang----------------
Even if we have a full team I'd make you favourites, because I simply can't trust or predict when this Arsenal team will decide to perform. We could make it a really competitive game, or we could just as easily lose a goal from playing out from the back, score an og, get a man sent off & lose 4-0!
