Arguably the biggest decision Gernot Rohr had to make ahead of Nigeria's friendly against Poland in Wroclaw on Friday was to decide on a starting goalkeeper.
The position has been a problem for the Super Eagles since Vincent Enyeama's retirement and Carl Ikeme's leukaemia diagnosis, but with the World Cup fast approaching, Rohr needed to identify a number one stopper - and stick with him.
Heading into this international break, the decision had appeared to boil down to either Ikechukwu Ezewa or Francis Uzoho, with the sensible money on the former.
However, perhaps influenced by Ezenwa's CAF Confederation Cup jitters for Enyimba, or his late arrival in camp, Rohr opted to hand Uzoho his first international start against Poland.
It was a significant show of faith.
To that point, the youngster had only played 45 minutes for the Super Eagles - as a substitute in the victory over Argentina - and has only featured twice for Deportivo La Coruna in the Spanish top flight.
Admittedly, he's a regular for Depor's second team - who play in the Spanish third tier - but this is hardly ample preparation for a showdown with Robert Lewandowski, let alone the World Cup and a group-stage meeting with Lionel Messi.
However, Rohr and goalkeeper coach Enrico Pionetti appear convinced by the youngster's pedigree, and have promoted him ahead of Dele Ajiboye, Dele Alampasu, Daniel Akpeyi and, apparently now, Ezenwa.
It was a mixed display by Uzoho, although he deserves credit for overcoming an uncertain start to make a series of fine stops in the second period and, ultimately, ensuring Nigeria won and kept a clean sheet.
The history books won't remember that Poland had a goal questionably chalked off either!
Of course, he doesn't have the familiarity with his centre-backs that Ezenwa was developing, and his inexperience was evident with some dubious positioning at times and the kind of hesitancy that can characterise stoppers wet behind the ears.
He flapped at several set pieces - the kind of errors that could be punished mercilessly in Russia - and Pionetti clearly needs to spend more time working on the wonderkid's kicking.
During the second half, it became easy to forget that Uzoho was 19, which is testament to the way in which his confidence grew during the encounter.
Credit must go to Leon Balogun and, especially, William Troost-Ekong for protecting their new young teammate, but as well as preparing for their maiden World Cup, the duo will now have to plan how to cover for Uzoho's various deficiencies between now and mid-June.
It's not impossible that Rohr will start with Ezenwa against Serbia in London, to give the hero of the qualifiers a chance to reassert himself, but at this late stage, he'd surely be wise to give Uzoho the playing time he needs to build on his showing against Poland.
Time is fast running out.
While Rohr must be applauded for taking the risk, acting upon his conviction and starting with Uzoho, it's a decision that threatens to undermine the Eagles in Russia.
While Ezenwa had a burgeoning relationship with the backline, and didn't concede from open play in two games against Africa's champions Cameroon, as well as bouts with Algeria and Zambia, Uzoho is playing catch-up from the off.
A combination of his lack of experience - both at club and international level - and his lack of familiarly with the Eagles defence set him apart as a weak link in a fine unit, and he's in danger of being exposed at the World Cup.
Rohr had to make a decision, of course, and was stuck between a rock and a hard place.
However, the decision to opt for Uzoho over the more familiar Ezenwa is a major gamble, and leaves the coach open to significant criticism if things don't go to plan in Russia.
