YORK CITY must not become a "yo-yo team" if they are to escape the League Two relegation trapdoor.

Manager Russ Wilcox, thrilled with last weekend's victory over Tranmere Rovers, has urged his side to keep their consistency - believing they will pick up results as long as they do so.

City are looking to make it three games without defeat at Sixfields against Northampton on Saturday and Wilcox said it had felt like a "different club" this week with players and fans buoyed by a morale-boosting home win.

He explained: "Everyone has got a spring in their step but it has been coming. Eventually, if you do keep performing well, the results do turn and there is no-one that deserves it more than the players.

"The hard work they have put in during this difficult period saw them get their rewards at the weekend. The only disappointment was that we didn't win by more. It was great to see us creating goalscoring opportunities and we could have had five or six.

"We have got to make sure now that we are not a yo-yo team, up and down, and that we are more consistent. If we are, we will pick up results."

Much attention has focused in the last two games on City's switch from 4-4-2 to a 4-2-3-1 formation but Wilcox has played down the move, arguing it is more about utilising key players differently.

"It sometimes makes me laugh - this change of formation - when it is just ten yards here and there," he said. "The main change has been getting different personnel in different areas of the pitch.

"Brad Halliday has come in to the centre of midfield and given us a lot of energy and a lot of legs. Michael Coulson is playing more centrally and has given us a lot more quality from both sides of the pitch.

"I think that's probably the biggest change. Coulson plays another ten yards up the pitch and it is a 4-4-2. There's lots of talk about formations and I don't want to go down the Man United side of things where suddenly he (Louis Van Gall) is a genius because he goes back to 4-4-2 against Preston when they have played 4-4-2 for the last 20 years under Alex Ferguson.

"I don't want to be that type of manager but I think it is just more about getting players in different areas of the pitch. That has enabled us to play a little bit more football, to give teams more problems. It is about being flexible and we have got to be flexible for the last 15 games and just find different ways to win."

Michael Ingham missed training today with a sore knee but the goalkeeper is expected to be fit for the Northampton game and Wilcox's biggest dilemma is whether to start returning loan striker Diego De Girolamo.

"It's difficult after last week's performance but sometimes you have to find ways," Wilcox said when asked how he would fit the Italian Under-20 international into his line up. "He is a top player and I think it will be shown in the summer when somebody takes him."

He added: "You have to look at everything but I have to make sure I don't look too deeply. The lads who performed last week were outstanding to a man. It is our best home performance of the season and it has certainly given me food for thought.

"But, either way I go with it, it will make the squad stronger. "

Northampton will be without play-maker John-Joe O'Toole, who is suspended, and are expected to bring in teenager Ivan Toney.

On the Cobblers, Wilcox said: "That will give us a different kind of problem. Instead of power and experience in there it will be more legs and pace. They will have to worry about what we do. How do they deal with Coulson in the hole if he plays in there or, if Diego is there, who deals with them between the lines?

"At the back the two centre halves are big and strong but lack mobility so it should be an exciting game. I watched the game against Dagenham and they were outstanding, right on the front foot after the first whistle.

"We have to make sure we put a marker down early doors. Our win last Saturday was based on a clean sheet and that's what happened so many times last season. If we can get back to that formula - solid at the back and creative up front - it's a good combination that allows you to win games."
