Lutui was also in the thick of the action as Tonga shocked finalists France with a sensational display in the pool stages.
However, the 33-year-old has vowed to put that all to one side and focus on life back at Sixways with Head Coach Richard Hill revealing that Lutui was pushing for inclusion against London Wasps.
"When I got back I was given time off by the coaches to get fresh - now I am just ready to get going," said Lutui, who features in The Warrior match day programme this Friday.
"The emotion from the World Cup is now over. I am getting my concentration right and seeing what I can contribute for the Warriors.
"It's going to be hard in the Aviva Premiership. The boys have done well in the last six games and we were disappointed not to get more results.
"For me, I now have to catch up really quickly and learn the calls. I want to nail down my role.
"I feel really good to be back, I have been away for a long time and nearly two months," he added.
"It is a good experience for me to play in the World Cup, now I want to give the energy from me to the team for the rest of this season."
