The goal was to end all confusion over player movement between the Singapore Under-23 team and the LionsXII, as the country enters the final straight of its preparations for the 28th South-east Asia (SEA) Games, which it will host from June 5 to 16.
In a shock development, however, it was announced at a media briefing by the technical team of the Football Association of Singapore (FAS) yesterday that Under-23 head coach Aide Iskandar had been warded for dengue fever.
It is not known how long Aide (inset), 39, will be out, but the FAS stated that assistant coaches Kadir Yahaya and S Subramani will lead the team while he recovers.
Despite the setback, national teams head coach Bernd Stange said in no uncertain terms that the SEA Games target was a place in the final, which will be played at the National Stadium on June 15.
Speaking to The New Paper, the German said all parties - the players, coaches and the FAS - are convinced it is an achievable target.
"We cannot say we don't have a high objective; we want to deliver at the SEA Games, and that is to play in the final," he said. "That target is important for the fans, the players, the whole country.
"This Under-23 team are the base of our future, and so we need a top performance from them."
Stange, along with Aide and LionsXII coach Fandi Ahmad, have agreed on a strategy involving four players that are wanted by both teams.
A 30-man Singapore Under-23 squad will enter centralised training on Friday and the SEA Games team will then head to Japan on May 10 for a week-long tour which includes two friendly matches.
LionsXII players Faris Ramli, Sahil Suhaimi, Christopher van Huizen and Zakir Samsudin will be made available, though, for the Malaysian Super League's side FA Cup semi-final first leg against Terengganu on May 9 at the Jalan Besar Stadium.
They will leave the Under-23s camp on May 7 and return to the fold before flying off for Japan three days later.
The quartet will not be available for the second leg of the Malaysian FA Cup semi-final on May 16 in Kuala Terengganu, but will be released again should Fandi's side qualify for the final on May 23.
