DIGICEL Fiji sevens head coach Alifereti Dere says he will need to work with individual players as they build-up to the Rugby World Cup Sevens.
With the International Rugby Board HSBC Sevens World Series getting tougher and tougher each tournament, the former national 7s captain said his troops needed to be on par with the modernised version of the abbreviated code.
He said he would maintain the 21-member squad and the only replacement would be for the suspended or injured players.
"I will work on each player's weaknesses when they return," Dere said.
"I have all the player's fitness data and from there I will see what each player lacks, then I will work on it.
"If any player lacks the upper body strength or endurance, we will make a training program to help them improve on that."
Dere said the IRB sevens series had improved and no team should be taken lightly. He said the weaker sevens teams had worked tirelessly to bridge the gap of sevens rugby.
"In the past, teams like Portugal, Scotland and USA were not very competitive. But now they have really improved a lot and we need to treat all games as a final starting from the very first pool game.
"The IRB series is getting tougher and tougher. We have to give our best from the first game until the last.
"So that is why we need to improve and prepare the boys individually to match the strength and pace of the sevens game," he said.
"I will maintain the 21-member squad for the rest of the IRB tournaments and to the RWC 7s and beyond that.
"We need to work on what we have now and build from here.
"The only changes will be made if players get injured or disciplined like what happened to Cakau (Setefano) and Manu (Laqai)."
Dere said he would wait for the manager's report before deciding if Cakau and Laqai could be considered for the Hong Kong and Japan 7s tournaments.
