Following Saturday's 34-16 defeat to South Africa , Reid knows a victory over Samoa this weekend will be enough to make it out of Pool B.
But Warriors forward Reid is keen to avoid any complacency at St James' Park with Japan waiting in the wings should they slip up.
"Everyone is saying it's a nothing match for Samoa but they will be determined to finish on a high," said Reid.
"They have a big physical pack who play straight rugby pretty similar to South Africa, so hopefully we will wear them down and our physicality will come through and get us the win.
"The South Africa game was a very physical one and it was a good settler for the boys in terms of getting us in good stead for Samoa.
"But there are a lot of areas we have to look at, and we have to make sure we learn from last week and do some things differently to make sure they go right.
"We know it is not going to be easy. They are big and physical and they have beaten us before but we will be fresh coming into the weekend and we will be ready."
