"We have to keep believing and believe things will change. Getting the right personnel out on the pitch is going to be the most important factor for the remainder of the season. It is important that we get the right personnel. In the mean time we are playing games and points are passing us by, and I am not happy with that situation, but it is like Groundhog Day.
"Look at the Cheltenham game. We shouldn't have lost the game, yet we have come away with nothing and their winning goal came from our corner and that is where the frustration comes in. I could go on, but people don't want to hear it, they want to see a change in fortunes.
"Calum (Willock) and Luke (Rodgers) will miss Carlisle. Marc (Richards) is having an MRI scan to ascertain the full extent of his injury. Jason (Talbot) comes back into the reckoning. Of course, the news could have been better.
"We're going to take a squad up and I'll have to decide on the formation and personnel. But whatever team you put out it's there to win a game of football. You can't always select the players that you want and you go through these phases. But we're not going to feel sorry for ourselves, we'll just get on with it.
"People are going to say it's got to be a banker for Carlisle but football is a funny game. Things can change and sometimes at the places you wouldn't expect. I'm sure Carlisle won't be treating us lightly. We don't want to be going to the big clubs in this division and bringing nothing back. We need to take something from those places."
Meanwhile Vale winger Joe Cardle, who has recently returned to Burslem after spending the last four months on loan at Clyde commented :
"Carlisle are a good team and are doing well. We have to go there, be positive, and hopefully get something out of the game. You can't go into a game all doom and gloom. I think I've brought a bit of confidence into the dressing room and have been trying to get the boys going."
As Sinnott has already mentioned the Valiants will be missing some key players tomorrow through injury, the main trio being strikers Luke Rodgers (knee), Marc Richards (ankle) and Calum Willock (hamstring). The absence of those three attacking players could see Vale's forward line tomorrow consist of 17-year old James Lawrie and 18-year old Danny Glover, who United fans will be hoping doesn't prove to be a lethal weapon. (sorry)
Left-winger Paul Edwards is rated as 50-50 for the game as he recovers from the sickness bug that saw him miss Vale's 1-0 defeat at Cheltenham on Wednesday night. In better news for ex-Farsley Celtic boss Sinnott, left-back Jason Talbot returns from the shin problem that also saw him sidelined at Whaddon Road while defender Mark McGregor is back after serving a one-match suspension on Wednesday for picking up five bookings in the season.
Two players who have recently left Vale Park are firstly 28-year old goalkeeper Mark Goodlad who has been forced to retire this week with an ongoing achilles tendon injury. Secondly, Southampton midfielder David McGoldrick, 20, went back to St Mary's Stadium after finishing a four month loan spell with the Valiants on Boxing Day.
Marc Laird, on loan from Manchester City, plays the last game of his temporary spell tomorrow before he returns to Eastlands, although Sinnott is looking to snap up the 21-year old on a permanent basis. Sinnott having already made his first signing of the January transfer window earlier this week with the return on a permanent basis of Manchester United left-back Adam Eckersley, Eckersley having already spent a loan spell at Vale Park in October before seeing it curtailed by a knee injury.
The referee for tomorrow's match is Mark Haywood from Wakefield in West Yorkshire, and he will be assisted down the lines by Darren Bond from Wigan and Ian Nolan from Rochdale. Meanwhile the fourth official will be Darren Handley who, like Bond, is also from Wigan.
