For the past two decades, when they were decked out in Nike gear, Singapore might have often drawn inspiration from the company's "Just Do It" slogan.
On Friday, as they unveiled their brand-new threads following a switch in kit supplier midway through their 2026 ASEAN Championship campaign, it is perhaps fitting that their new partners Adidas always say that "Impossible Is Nothing".
After all, many probably did not give them a chance of reaching the semifinals, especially given they were drawn in what looked to be the Group of Death alongside defending champions Vietnam and emerging force Indonesia, who were the only Southeast Asian team to reach the third round of the Asian qualifiers for the 2026 FIFA World Cup.
But with the odds against them and their backs to the wall, the aptly-named Lions produced a stirring display at Jalan Besar Stadium to force a 1-1 draw with Indonesia -- securing a top-two finish in Group A and a place in the last four in the process.
Singapore coach Gavin Lee's desire in wanting his players to always believe they are a chance as long as they are still in the contest illustrates a newfound belief within the team. They certainly proved it on Friday.
With just two minutes on the clock, Singapore could easily have fallen behind. Miscommunication between goalkeeper Izwan Mahbud and Jacob Mahler presented what was effectively an open goal to opposition striker Mitchell Baker from a few yards out. It was a chance that would have been converted nine times out of ten.
Refusing to give up, a recovering Shah Shahiran toiled back towards his own goal and somehow denied Baker with an incredible sliding block just two yards from the goal line to deny the Indonesians -- who needed to win to progress -- a perfect start.
Then, when the visitors had finally broken the deadlock in the 47th minute, Singapore looked to be on the ropes 11 minutes later when midfielder Song Ui-Young was sent off after being shown a second yellow for his reaction to a cynical foul on him by Ivar Jenner.
Although he eventually made his way off the pitch reluctantly, Song did not head for the dressing room just yet. He was adamant he had not deserved another booking. Metres away, Lee remained a picture of calm despite the impending setback.
VAR would come to the rescue, with the referee deciding -- upon second viewing -- that the contact Song had made to Jenner had not been aggressive enough to warrant a caution. Singapore's midfield dynamo was allowed to rejoin proceedings and -- by the 66th minute -- when Indonesia goalkeeper Cahya Supriadi and captain Rizky Ridho had a mix-up of their own, Ilhan Fandi pounced to score what proved to be the crucial equaliser that would send the hosts through.
There were heroes for Singapore all over the pitch when the final whistle blew, but perhaps none epitomised the resilience they now boast more than man of the match Mahler.
Prior to the start of the tournament, the 26-year-old had just 17 caps to his name. He had to bide his time with substitute appearances in Singapore's opening two victories over Cambodia and Timor-Leste.
Yet, in the daunting trip to Hanoi's Mỹ Đình National Stadium to take on Vietnam, Mahler was introduced by Lee to the starting XI to play alongside captain Hariss Harun in the heart of defence. He had his hands full all evening long, primarily against the imposing Rafaelson, but would play his part in a stirring 0-0 draw.
Again, against the Indonesians, Mahler showed determination to recover from almost giving up an early goal by constantly put his body on the line in a bid to get his team over the line -- hardly no surprise given he had mentioned on the eve of the match that he was prepared to "basically die for the badge".
"As the coach said, the biggest thing is belief," said Mahler. "That is something we need more of whenever we enter matches: believing in our capabilities. Going unbeaten through the group stage is not easy.
"It starts with the coach and captain and extends throughout the entire team. We are a very close group, from the backroom staff and coaches to the players. We have an excellent relationship with one another.
"We have experienced many ups and downs together, and those experiences have brought us closer. It is easy to talk about fighting for one another when you are enjoying some success.
"However, even during the difficult moments, we stayed together. That is where this spirit comes from.
We have been through a lot, and I think everyone involved in Singapore football understands that. We all share the same objective: we want Singaporeans to have a national team they can be proud of.
"Every time we step onto the pitch, that is our mindset.
In Lee's relatively short time at the helm since he took over -- initially on an interim basis -- last June, Singapore have display an uncanny ability to respond to setbacks. Their coach often espouses the "keep calm and carry on" mantra.
There was 101st-minute winner by Ilhan against Cambodia, just when it looked like the Lions were going to get their campaign off to a slow start. There was also the famous triumph in Hong Kong that sealed a first AFC Asian Cup qualification on merit back in November, when they came from behind after conceding in the 15th minute for a 2-1 victory.
Now, there is also a rousing revival against Indonesia that sealed a second consecutive semifinal appearance at the ASEAN Championship.
"It was obviously not the greatest start to the game," admitted Mahler. "It was a lapse in concentration on my part, and I take responsibility for it. However, these things are part of football.
"We have a philosophy within the team that, whenever something goes wrong, the focus has to be on the next action. That also applies beyond football.
"When you are knocked down or something goes wrong, you simply have to keep moving forward. I tried to put that moment behind me and continue playing.
"Thankfully, Shah [Shahiran] made an excellent block, and I owe him a lot for that. I just pushed on from there, and thankfully we came out on the right side of the result tonight.
"It was an amazing atmosphere. We were also wearing the new kits and, with National Day coming in two days, there could hardly have been a better way to begin the celebrations.
"We are over the moon and wanted to give Singaporeans something to celebrate. However, our full focus now turns to the semi-finals.
"First, we have to recover, and then we want to give ourselves the opportunity to play two more finals after the semifinals."
In a bygone era, when they were wearing their old uniforms, maybe it could be said that Singapore went out and just did it.
Now, in their shiny new kit, perhaps genuinely impossible is nothing as they move their attentions to the semifinals of the ASEAN Championship -- and maybe even further.
