The 43-year-old Spaniard has a proven recipe for success after guiding his Auckland City side to six OFC Champions League titles in a row.
Tribulietx, who joined the Solomon Islands squad’s training camp in Sydney last week, insists confidence is a key ingredient.
“The Solomon Islands have a lot of very talented players and we hope they can express themselves in Papua New Guinea.
“We have worked on everything, attacking and defending, the conditioning side of things, and on the mindset and mental strength of the players,” he says.
“We were looking to build some confidence and belief going into the tournament.”
Tribulietx says national team coach Moses Toata has built a system that will serve his players well.
“I am a very late addition to the party and I needed to learn quickly how they operate.
“I purely advised on the different aspects of the game based on the principles and structures that they have already set up.”
Tribulietx believes the Sydney camp has been a successful exercise and the team is well prepared for the tournament.
“We didn’t have much time but we had to make sure the team is organised for the tournament,” he says.
“I think the players have enjoyed their time together as well as the training and they are physically and mentally ready.”
The Solomon Islands will depart for Port Moresby on Wednesday.
They will open their 2016 OFC Nations Cup campaign against Vanuatu on 28 May.
