Tuala has been in sparkling form in this year’s competition, and retains his place in the team from that which came from behind to beat Canada in the final round of pool matches.
Fotuali’i meanwhile is coming into the side for his first outing in the 2015 edition of the tournament, and his first appearance since helping Samoa run the All Blacks close in Apia last month.
Also in the team is former Saint Fa’atoina Autagavaia, who comes onto the wing. Other familiar names from the Aviva Premiership include Alesana Tuilagi, who captains the team, props Sakaria Taulafo and Anthony Perenise (former Wasps and Bath respectively), Sale pair Johnny Leota and TJ Ioane and Newcastle wing Sinoti Sinoti.
The Pacific Nations Cup final will see Samoa go head-to-head with Fiji in Burnaby, British Columbia, just a few days after they played out a thrilling 30-all draw in the second round of pool matches.
Earlier in the day the tournament’s joint hosts, the USA and Canada, will meet in an all North American clash, with Japan coming up against Tonga to decide who takes home the wooden spoon.
All of the action can be followed at www.worldrugby.org/pnc, with Samoa v Fiji kicking off at 1am on Tuesday morning.
