I think that's a fair thing to say. On their day, Arsenal can do that to any team - even established PL teams. If you're slightly off your game, and they're right on it - bang. They created shed loads of chances yesterday, but weren't as clinical (typically).
Overall though, we've had a tough start but I think we've aquitted ourselves really well and - apart from the blemish of the Arsenal game - we've not really looked out of place against anyone.
I'd worry more for Reading. They've had a pretty easy start fixtures wise, compared to us, but they're in a worse position. They don't score goals on the whole, or create many chances. That's why I think we'll be ok - we always create chances, against any team, and as long as we continue to do that we will win more than we lose.
It's still hard to judge anything yet, give it until around November time and I think it will all start taking a little bit of shape.
