Belgium head coach Roberto Martinez believes his side are stronger now than they were three years ago when they made the 2018 World Cup semi-finals.
Martinez's side, who are currently first in the FIFA rankings, will play their World Cup semi-final conquerors France in the final four of the Nations League on Thursday.
After their third-place finish at Russia 2018, Belgium were beaten by Italy in the Euro 2020 quarter-finals in July, prompting suggestions the Red Devils' golden generation had missed their chance for silverware.
Martinez's starting XI in their World Cup semi-final defeat was the oldest (28 years, 356 days) of all of Belgium's line-ups during the tournament, which some might argue was evidence of them being at the peak of their powers.
Between the start of the last World Cup and the present day, Belgium have named a starting XI with an average age of 29 years or more nine times – seven of those have been in 2021 alone.
"I think I would like to believe that we are stronger just because internally I do feel that we can cope with more players when they are suspended or they are out of the squad," Martinez said during a news conference ahead of the clash with world champions France in Turin.
"I think the pool of players for Belgium now has grown, and as well, an extra three years that we've been able to play together.
"That's what synchronises us, something that you haven't got a lot of in international football. I think we always try to have a certain continuity with the players and try to work like you would do in a club environment.
"The understanding between the players is a lot better. We've been through a lot together. In terms of experience and the pool of players, I believe that we are stronger than we were in 2018."
Martinez conceded France had also grown from their 2018 triumph, citing Kylian Mbappe's evolution into a world-class talent along with the re-emergence of Karim Benzema after international exile and Paul Pogba's return to form.
"I would believe that if you'd ask [France head coach] Didier Deschamps this, he'd also say that his team has improved as well since 2018," Martinez said. "I think this generation in French football, they've got probably three elite footballers per position."
Martinez was full of praise for Belgium forward Romelu Lukaku, who spoke out about his dislike of his tag as a "target man" earlier this week.
Lukaku, who moved from Serie A champions Inter to Champions League holders Chelsea in August, has netted eight times in Belgium's past eight matches and Martinez praised his all-round threat.
"Romelu has become a number nine that can do everything," Martinez said of Belgium's all-time leading scorer. "He can play with his back to the play and run in behind.
"He's got the power, the pace, he's got the understanding of combining with other players as someone that can play with the pace and power, but with intelligence as well.
"I think at his time at the end in Italy with Inter Milan, give him another degree of maturity as well. You're talking about player that is now at the height of his career and his outstanding knack is always scoring goals."
