Footballers are often best remembered for what they do on the pitch, whether it be a devastating 30-yard strike, and inch-perfect through ball, a perfectly timed slide tackle, or a breathtaking fingertip save.
However, none of that would be possible without the work put in on the training ground. The efforts behind the scenes often goes unnoticed, but it's in practice where players develop into superstars.
Here are some of the world's most impressive training grounds.
9. St. George's Park
St. George's Park opened for the England national team in 2013. This action was quickly proceeded by the miserable failures at the 2014 World Cup and Euro 2016. But hey, it looks pretty from the outside, and then the women's team made consecutive World Cup semi-finals. And the men's team made the 2018 World Cup semis. So.
8. Etihad Campus
The Etihad Campus is the most expensively assembled training complex in world football, belonging to Manchester City. And...yeah, as you'd expect, it's very impressive.
It has six outdoor pitches, 80 bedrooms, and a 7000 capacity stadium for the academy. Although I suppose that's the least you'd expect for $244.2m.
7. Ciudad Real Madrid
If it's good enough for David Beckham and Cristiano Ronaldo, then it's good enough for this list.
The centre has about a million different rooms, 12 full size pitches, and a whole load of other facilities. But, most importantly, it has the Alfredo Di Stefano Stadium, where Real Madrid are currently playing their home matches during the coronavirus pandemic.
6. Chennaiyin FC
Sure, the grass looks like something out of Sunday League, but those palm trees more than make up for it.
5. Davao Aguilas
You've probably never heard of the Filipino side Davao Aguilas FC, but they're making moves.
Their new stadium and training facility is still yet to be completed. But when it's done, it should be a beauty.
4. Power Training Complex
Okay, the facilities themselves look a bit meh. But that bridge, eh? Gorgeous.
The Power Training Complex belongs to MLS side Philadelphia Union, and is right next to their home stadium, Subaru Park. From inside the ground, spectators get a great view of the Commodore Barry Bridge and Delaware River.
3. Lennoxtown Training Centre
Playing in front of 60,000 loud and passionate fans every week? Pretty cool. Playing in front of a castle every day? Even cooler.
The Lennoxtown Training Centre is the facility used by Scottish giants Celtic. It's safe to say they've got the silverware to match the view.
2. Guangzhou Evergrande Academy
If you think a castle or a bridge is impressive, have a quick watch of THIS.
50 pitches, 2500 players, and a whole load of money poured into it. This absolute behemoth belongs to CSL side Guangzhou Evergrande, and is part of a project to make China successful on the international stage.
1. Ciutat Esportiva Joan Gamper
It's all well and good having a pretty training ground, but ultimately it's all about who you're producing from it.
The Ciutat Esportiva Joan Gamper is home to one of the most illustrious academies to ever exist - Barcelona's La Masia. Lionel Messi, Xavi, Andres Iniesta, Carles Puyol - all of them became who they were at the Ciutat Esportiva Joan Gamper. How many other training grounds can beat a record like that?
