Ah, rain, the old enemy.
No one like to think about it too much - especially after a wet season - but even the best summers have rain days. That means we need to plan for the weather.
Last year, West players got into a late season habit of having a net when a game was rained off. That happened a lot! I think mostly it was frustration at barely getting to play in July and August.
But it's also a powerful habit.
Nets are a competitive advantage we can exploit while other clubs head back home when the game is off. An extra hour in the nets might not seem like much, but it's an hour more than anyone else.
What are we telling the world and each other about how much we care by doing that?
It's one small difference, a "one percenter" that doesn't mean much in isolation, but when you add each on of these good habits up, it starts to make a difference on the pitch. One percenters like training on rain days don't require luck or talent, they just require the desire to form a useful habit.
Because remember, performance is a behaviour.
So, let's make it a mantra this Premier League summer...
If it's raining, we're training!
