Nigeria's 1-0 friendly victory over Poland in Wroclaw was both a magnificent boost for the Super Eagles as they approach the World Cup, and a valuable insight into Gernot Rohr's current plans for the showpiece in Russia.
Which Super Eagles boosted their prospects of making the cut or of playing a pivotal role this summer, and who could be set to drift to the peripheries over the coming months?
Winner: Francis Uzoho - The wonderkid was handed an unexpected starting berth for the meeting with Poland and the showdown with Robert Lewandowski.
This was already a major demonstration of faith from Rohr, with Uzoho having only made two La Liga appearances and played 45 minutes of international football before the trip to Wroclaw.
Despite a nervous start, he steadily grew into the game, and kept the Bayern Munich hitman at bay with a fine stop after the break.
There are concerns about starting with an inexperienced 19-year-old between the sticks at the World Cup - and there ought to be - but if Rohr starts Francis against Serbia on Tuesday, then it's yet further confirmation that he's primed to take the plunge with the starlet.
Loser: Ikechukwu Ezenwa - If Uzoho is one of the 'winners' from Friday's clash, then Ezenwa has to be considered the big 'loser'.
The goalkeeper had stepped into the breach following Vincent Enyeama's international retirement and Carl Ikeme's leukaemia diagnosis, and had looked primed to start in Russia after playing a key role during the qualifying campaign.
He also shone at the African Nations Championship, but a combination of his small stature, his error in the 1-1 draw with Cameroon and his inactivity with Enyimba appears set to count against him as Uzoho comes to the fore.
Winner: Joel Obi's timing hasn't been great throughout his career, with injury affecting him at various critical moments.
Notably, he missed out on the 2013 African Cup of Nations and failed to make the cut in 2014, while his chance to establishing himself at Internazionale were consistently undermined due to fitness concerns.
Now back and impressing with Torino, Obi might have finally got his timing right, and he did enough in his 65 minutes against Poland to suggest that his technical quality and versatility may have a role to play in Russia.
Loser: Elderson Echiejile missed out on Brazil 2014 after suffering an injury on the eve of the tournament, having previously been a key figure in Stephen Keshi's Nations Cup-winning team.
While he'll likely make the squad this time around, Rohr's decision to start Brian Idowu on the left ahead of Elderson was an indication that he's assessing other options.
It's a choice that may go down well with some portions of the Nigeria fanbase, many of whom don't have faith in the Sivasspor, and Idowu's impressive display - coupled with his excellent cameo against Argentina in late 2017 - boosts his World Cup prospects.
Winner: William Troost-Ekong - Unlike some of the other players on this list, Troost-Ekong's spot in Rohr's staring XI has never been in doubt.
Indeed, the centre-back will be one half of the 'Oyinbo Wall' alongside Leon Balogun that ensured Nigeria have enjoyed such a superb record under the German tactician - losing just one game (and one in which the duo didn't feature).
Against Poland, Troost-Ekong demonstrated another element of his game, as he captained the team in Wroclaw in John Obi Mikel's absence.
Like Uzoho, Troost-Ekong was shaky initially, but he grew in composure as the contest wore on, and appeared to relish the challenge of negating Lewandowski's threat.
He was vocal and calm as Poland sought to level the match, and while he cannot replace Mikel's on-field contribution, he'll certainly bring leadership to the defence at the World Cup, and take responsibility when the chips are down.
