Belgium are currently in the midst of a golden generation when it comes to their national football team.
The vast array of talent that lined-up at the 2018 World Cup all over the pitch bordered on insanity, with Thibaut Courtois between the sticks, Toby Alderweireld and Jan Vertonghen at the back, and the likes of Kevin De Bruyne and Eden Hazard pulling the strings in the final third.
But if there's one player who is potentially irreplaceable in Roberto Martinez's line-up, it's Romelu Lukaku.
Lukaku had a great start in Russia, notching braces against Panama and Tunisia, but failed to hit the net against the likes of Japan, Brazil and France in knockout games.
That's not a slight on the 25-year-old, who has been prolific at club level for West Bromwich Albion, Everton and Manchester United for the last six seasons.
But there was an argument to be had that Lukaku was a 'flat-track bully' on the world's biggest stage, and the fact that he couldn't score against Brazil and the eventual champions France furthered the claims.
It isn't as though Belgium have a natural replacement or successor right now to Lukaku. Christian Benteke could have been challenging for a place had he not fallen off the radar in 2017/18 at Crystal Palace, and Michy Batshuayi has never been given much of a chance at Stamford Bridge to prove himself.
So Lukaku's comments to Business Insider about his plans on the international stage will surely leave Belgium fans worried in the long-run.
"After the Euros [in 2020], I think I'll stop," said Lukaku.
'I'm 25, I'm like, I'm not even in my prime yet. So I still see them [young players] as competition right now because they try to take my spot and I don't want to give it up to them.
"So like another two years, and then they can have it."
Statements like that will definitely worry Martinez, who won't want to lose his star striker if he plans on staying at the helm for several years.
It might come as a welcome surprise to Manchester United fans though, as it will see Lukaku play less games as he hits his prime years in a Red Devil's shirt.
Whether Lukaku fulfils his plans remains to be seen, and if he does, it would be a catastrophic shame to world football if one of the best goalscorers on the planet hung up his international boots at the age of 27.
