In case you didn't already know, it's been Leicester City's week.
The Foxes became the most popular Premier League winners in history – and one of biggest underdog success stories of all time – when they became English champions this week, overcoming 5,000/1 odds.
Their players went viral for recording their celebrations on social media – and it's a trick that Atletico Madrid, Real Madrid and Liverpool took when they became European finalists this week.
It's been a week of celebrations. Here's this week's best football pictures from Instagram.
