It's a good time to be a new stadium enthusiast .
Atletico Madrid and Atlanta United have both begin life in their new homes this week, as the ribbons were cut on two hugely impressive grounds.
The Spanish side bid farewell to the history-steeped Vicente Calderon at the end of last season and made their bow at the Wanda Metropolitano last weekend.
And while the 67,703-seater arena certainly looks the part, the Mercedes-Benz Stadium in Atlanta which plays host to MLS side United and the NFL's Falcons is even more impressive.
Offering an eight-part retractable roof and 360 degree video screen, the Falcons made their first appearance on Sunday night, seeing off the Green Bay Packers to kick off with a win.
But what other new arenas have we got to look forward to in the coming months/years?
Here are some of the grounds that are currently being constructed...
Tottenham
Here's one that we'll all be very familiar with this time next year. Tottenham will move into their shiny new stadium - currently dubbed the Northumberland Development Project - at the start of next season.
The £750million ground certainly looks the part, with a capacity of more than 60,000 and a retractable pitch that will be used for NFL matches, after a ten-year deal to play two games a season from 2018 onwards.
Chelsea
Joining Spurs in the new stadium-front in London will be Chelsea who have got the green light for their £500million project.
The striking 60,000-seat ground should be ready for the 2021-22 season and was designed by the same firm who did the Bird's Nest stadium used at the 2008 Beijing Olympics.
Los Angeles
After going two decades without an NFL team, Los Angeles is now home to two sides. The Rams and the Chargers will move into this Inglewood stadium that will seat 70,000 for regular season games and can be raised up to 100,000 for Super Bowls, Olympic Games and whatever other sporting events the city can claim.
Valencia
Construction on the Nou Mestalla has stalled in recent years, with Valencia unable to stump up the finances to get it over the finish line.
Building at the site ground to a halt in 2009 and despite scaling back the plans in 2013, no date has been set for work to restart on the half-finished ground.
Barcelona
Cheating slight here, as this is a redevelopment rather than a new stadium. The Nou Camp is currently undergoing a £500million do-over, which will see capacity increased to 105,000.
Russia World Cup 2018 stadiums
For stadium fans, a World Cup tends to mainlined joy and next summer sees a number of impressive new arenas take centre stage...
Saransk: The Yubileyniy Stadium will hold 45,000 and features a nifty, patriotic red, white and blue facade.
Samara: Another 45,000-capacity ground, Samara Stadium has a distinct lattice effect.
Nizhny Novgorod: Yet another 45,000-seater... is that a lucky number in Russia?
Kaliningrad: A solid, if not spectacular design, this one:
Rostov: The Levberdon Arena has seen its design change from the opening plans, settling for a less ambitious roof, which is a shame.
Volgograd Arena: Another 45,000-seater, which is currently being upgraded.
World Cup 2022 stadiums
Say what you will about the 2022 World Cup being award to Qatar (and there's plenty to say about that), it has produced some of the most out-there stadium plans we've seen yet.
While all details are not yet finalised, here is a selection of the best designs...
Lusail: This shiny 80,000-plus capacity ground sure looks pretty.
Al Khor: There are a few designs doing the rounds for Al Bayt Stadium which will hold 60,000...
Al Wakrah: Who remembers the film Flight of the Navigator? The designers of the Saoud bin Abdulrahman Stadium obviously do, as they've taken inspiration from design of the 1986 film's spaceship. Which is no bad thing.
Doha: The Khalifa International Stadium is one of a number in the Qatari capital and features a quasi-Wembley arch. Construction has been completed.
Doha: The Thani bin Jassim Stadium is being expanded... and the colours will match the teams who will play in the stadium, which is nice.
Doha: The snappily-titled Education City Stadium will hold just over 45,000.
Al Rayyan: There's an ethereal quality to the plans for this 40,000-seater.
