The United Gaffer says that he will chop and change the personnel for the game against the Valiant's. Some of the players who haven't played a competitive game will get their chances to shine tomorrow night.
"There are no new injuries but there will be changes. I definitely want to win and we will put out a very string side - we have the strength in depth to do that," said Blackwell.
"I think I need conformation from a couple of players who have not played for me in a competitive match that they have a future at this club. Pre-season fixtures are all very well but Vale will be very competitive and provide the test I am looking for.
"It is essential that we be on our toes and, in the build-up, make sure that everything is prepared in the right way or we could end up with egg on our faces."
