Arsenal always look like garbage after international breaks, I am not sure why though it is something I have noticed. I haven't looked at our record, but I would be surprised if it was over .500 in the first game after the break.
Arsenal wasn't going to finish the season without any losses, so it is naive for the anti-Arsenal to laugh at them losing. Same like how United and Spurs aren't going to finish the season without any losses either, both will have have setbacks. Arsenal still have a game in-hand everyone else and still control their own destiny. If they lose out on top four, then it will be their own fault and not an outside reason. I very much dislike the injuries though, Tomi and Tierney could put Arsenal in third place by themselves. Cedric has been a warrior for the past month, but the problems get exacerbated when you have to start him and Tavares (who's fallen off a cliff in terms of form lately).
