But, as ever, it's not actually as simple as that.
We've shown fairly decent aptitude against teams whose main intent is to attack us - Chelsea, Man United, Leicester to an extent - but struggled against teams who set up more conservatively. Especially at Old Trafford at the weekend, and in the first halves against Chelsea and Leicester, there wasn't a whole lot of boring or slow anything. We played at a good tempo and created a fair number of chances against both sides. We won at Chelsea and could easily have done so at Man United.
The issue is how we break down teams who sit very deep and deny any space in the channels. Our crossing isn't good enough to exploit wide areas - Perraud got into loads of good positions last night but so many of his crosses ended up going straight into David Raya's arms, which was infuriating as he's generally one of our better players in that regard. When teams pack the defensive block, there aren't many sides who are good at picking holes through the middle (City probably the only ones, really, and even then we've found success against them in the past by simply overcrowding them within the width of the penalty area) so you then get forced into wide areas, which is where you need a) the delivery to be of a high standard, and b) enough targets in the penalty area capable of getting on the end of those deliveries. Under Ralph in the first half of the season, we probably had the deliveries covered, but didn't get enough players into the box to convert, and when we did get chances we missed them (that Newcastle game is still infuriating after basically missing two open goals); now we've probably just about got enough players in there, especially last night, but the quality of the delivery and - in fairness to the wide players - movement wasn't up to it.
Brentford weren't any great shakes last night, IMO, but they had studied our weaknesses from wide set pieces where everyone gets drawn to the near post leaving ourselves short-staffed at the back post, and having given us a couple of warnings we still didn't take the hint and they scored from the third such opportunity.
