@Footy I mean, you guys are looking good but its way too early to scream victory, if you had a one or two run of poor games, you could be overtaken by City, Tottenham or even Newcastle.
As for transfert, doubt Arteta will bring a lot of new players, would suck to shake the team balance and hurt the cohesion they got going. Beside, they already spend a lot (for their standard) in the summer, I kinda doubt they will have much budget in the winter. Remember Arsenal just not that kind of team sadly.
Its also worth mentionning that player might be affected by the world cup and not come back in the same disposition. Hopefully, that could be true for other team as well but there is a risk its hurt Arsenal current form. Now, on the positive side of thing, Odegaard not going to the WC (like Haaland) mean he can rest and prepare for the next game at Arsenal.
Do I think Arsenal can win the league this season? Yes, I actually think they could do it. But it require a couple of thing, one of these thing is that they keep up the momentum despite WC, another one is that City doesn't start going on crazy run where they win 5-10 games in a row and finally, that Tottenham stop getting away with what their doing because right they are very close behind despite winning lots of game by the skin of their teeth.
Now it looks really convincing that we will finally win the league again. If we get 3 top players that we need in January, then it will basically be gauranteed.
