"We can work with a smile on our faces this week and I will definitely be making changes next weekend," said Yates.
"Hopefully we will take a big crowd down to Plymouth and I'm sure there will be a bumper crowd.
"One or two deserve a chance and a few need a rest too. It will do us the world of good knowing we have secured it."
