You didn't have to be eagle-eyed to catch a glimpse of Pep Guardiola's eye-catching wardrobe change for Manchester City's visit to Arsenal.
Normally sharply dressed in a shirt and tie or fashionable jacket, the City boss did away with the formal get-up for his side's trip to London - and in its place was a hoodie that got the internet talking.
But while the shirt, shoes and sweatshirt combo raised a few eyebrows, it turns out the Catalan boss was simply doing his bit for charity.
The hoodie repped Open Arms, a non-profit organisation based in Catalonia, dedicated to helping refugees who attempt to reach Europe by sea.
It's a cause Guardiola has batted for in the past. Though it went largely unnoticed at the time, he wore a similar hoodie for the Boxing Day win over Newcastle earlier this season, and that prompted Oscar Kamps - owner of Open Arms - to reveal he donated €150,000 to the cause back in 2018.
Discussing the impact of Guardiola's generosity, Kamps said (as quoted by Showsport): "Guardiola came to us in 2018 and offered help in the amount of 150,000 euros out of his own pocket. The support of other athletes who also wanted to contribute helped us achieve the goal of getting the ship back on track."
If you're feeling charitable and fancy picking up your own version of Guardiola's latest fashion statement, it is available to buy on the Open Arms website. You can also buy T-shirts, face masks, tote bags, mugs, water bottles and badges...or just donate if you're feeling generous.
The hoodie certainly seemed to be a good-luck charm for Guardiola, who watched his side pick up their 18th successive win thanks to Raheem Sterling's salmon header early in the first half.
After a hard-fought 90 minutes, it was a win Guardiola welcomed...with open arms.
I'll get my coat.
