Nah, you're being too positive based on your defence of Ten Hag. We play like that again for 90mins and we'll drop more points. Simply nowhere near good enough.
It's not even a defence of Ten Hag, it's just a basic analysis of the game. We had way more shots, possession, territory, and general attacking intent, which resulted in better chances, a higher xG, etc. Brentford set out the same way Palace did last weekend, aiming for a point, hoping to nick a goal, which they did, and sit on it. The difference is, we actually made our chances count, eventually.
We do need to work on our ability to unpick parked busses, no doubt, teams are able to shut us out too easily at the moment. But there's a reason teams adopt that tactic, because it works, this is the same Brentford team that did the double of City last season with the same approach.
