"Ikale Tahi doesn't have a lot of opportunity to play against tier one nations - this is our only tier one test this year - and Tonga have never beaten Wales, so there is an opportunity to create history," said Doorey, in his first campaign with Tonga.
Motivation will be high, especially as this is the key lead-in test match to Pacific Nations Cup/RWC qualifiers fixtures against Samoa and Fiji. The squad is sure to get a rousing homecoming as it will be their first matches in Nuku'alofa in nine years. But time is short to meld players from the UK, France, Japan, Australia and New Zealand.
"Five days is not a lot of time to prepare for a test match, so it's all about maximising your time together and coming up with a simple game plan," said Doorey.
He does not buy into the theory that Wales are ripe for the plucking.
"They'll be looking at this group of players that may project them forwards to RWC 2023. Some will want exposure for 2019.
"Guys like Gareth Anscombe, Jamie Roberts and Alex Cuthbert may have been reasonably close to Lions discussions, so we are not underestimating their quality at all," added Doorey.
Tonga won all three of their November tests against Spain, USA and Italy after a winless 2016 PNC.
They will name their match-day 23-man squad today.
