Trying to find a chink in Manchester City's armour is like looking for a needle in a haystack. If it does exist, it's barely detectable. Andree Jeglertz's impact has been profound in that sense.
City did not need to revolutionise the way they worked to reach this point, only the way they thought. Before Jeglertz, title talk was taboo. Under him it's mandated to such an extent it's written on the walls of their training base.
Because how does one learn the habits of a champion if the subject is not part of the everyday playbook? The Swede never considered the Women's Super League title aspirational, even in year one. How can it be at a club like Manchester City? All the tools are there.
Except of course winning silverware is not always the reserve of the club's with the best resources and most versatile talent. Nor should it be. That is what keeps football exciting. And, crucially here, what drives City's group to want to reinvent ways football matches can be won no matter the circumstance.
Pretty football. Tick. Threat from open play and set-pieces. Check. Stacks of goals from all over the pitch. Mastered. What else?
Perhaps the only critique of this near-perfect side is how they perform when they meet proper resistance. That is to say, when an opponent is so unyielding it renders their style of football, Jeglertz's preferred method, ineffective. Do City have a robust Plan B? And if they do, does it work against the best?
Off the back of scrapping to an important victory over London City Lionesses by less conventional means, Mary Fowler, who assisted the winner, explains City's new edge. "The way we won it, it was not our best performance in any way. But we won using a different style.
"All the girls knew the shift they would have to put in. There were loads of chances created against us but we put bodies on the line. We saved opportunities. Sometimes those kinds of wins feel deflating but we should actually celebrate it more.
"It was such a big shift for us to have to hold onto a win. It's a great mentality to keep belief until the bitter end. This group should be proud of that."
Man City's 2-1 victory in Bromley a fortnight ago was the first real examination of this new contingency plan in action. There were pinch-points towards the backend of last season where cracks appeared - losing to Brighton and getting lucky to sneak past Liverpool - but City remained in control of the title race.
Because actually it's often the year after winning a championship that is famously hardest.
City are having to find ways to adapt. Lauren Hemp called it 'winning ugly' last weekend, which is not a concept synonymous with the club or its manager. But is one that holds great reward if can be relied upon in small doses. Detaching gold standard performances from positive outcomes is something only elite sides can do.
"It's not our intention to win games that way," Fowler continues. "It always feels nicer when we have won in a way that feels comfortable. But being able to win ugly shows another side to this team. We aren't going to give up, we won't stop fighting for momentum and that one moment that can decide a game.
"That is something we showed in parts last season, we scored a lot of goals late in games. Whether it's an addition, or it's something we haven't had to use that often, I think it's a great quality to have and to recognise. It's good for confidence."
Chelsea, City's next opponents, used to be masters of this underrated art. Under Emma Hayes, the Blues were run like robots. In a good way. It made them domestically untouchable, such was their conviction to win by any means. Almost at any cost.
City have begun to lean into their example. "We love playing beautiful football but sometimes you have to scrap. Just because we have a plan to play a nice style doesn't mean it will always work. We have to have a fallback quality, even if it's messy. It's about getting stuff done."
But this not a copycat move. It's simply a pragmatic one, which safeguards against times where playing progressive football is less possible. In a meeting of the only two remaining unbeaten sides this weekend, an alternative strategy might come in particularly handy. "We're in a great place but we're fuelled to want to perform even better," says Fowler.
City have won just one of their last nine trips to Chelsea. Six of those were losses. And they arrive to a side that boast the best shot-per-90 rate of any team in WSL history. "It's a big game and a great match-up. Some wins have lacked performance so far but we have all the tools we need."
Jeglertz's side have already been made to endure this season. Their comeback victory over Arsenal in October was another example of the gritty nature by which results have been impressively ground out. City have already conceded double the amount of goals Chelsea have this term, and yet, are two point clear at the top of the table.
To be comfortable in the uncomfortable is definitely something new. Perhaps that makes the reigning champions more uncompromising than ever.
