Keith Curle says he will sign a new contract at Carlisle United when he is “100 per cent happy” that his vision is shared by the club.

The manager, who leads the Blues to Plymouth tomorrow in the FA Cup first round, is in negotiations over an extension to his deal at Brunton Park.

While the club this week insisted there was “no panic” over the ongoing talks, Curle said the detail of a potential agreement was still to be finalised.

And he suggested that his ambitions at United were among the key issues to be settled with the club’s hierarchy.

Curle said: “With every player I sign, I tell them not to sign until they’re 100 per cent happy with everything that’s in place. Read the small-print.

“That’s the stage we’re at. Both parties have got to be 100 per cent happy with the commitment from both parties, and also the vision both parties have got, individually and as a collective.

“There’s no point saying I want to be managing in the Championship in a period of time if there’s not a realistic vehicle that the club can get there.

“It’s a case of everything having to be right for both parties. That’s a credit to the club. They want to make sure their vision and the role they have for their manager is right for them - that the manager is able to enhance the vision they’ve got and also take the club as far as they think they can go.

“There is no need to shy from the fact that neither party will sign something that isn’t right for both. It’s important both have that shared vision.”

Curle has impressed with his rebuild of the Blues this season, which has put them just outside the play-off places after 16 games in League Two, having achieved a memorable Capital One Cup run to Liverpool and now eyeing progress in another competition.

They confront the League Two leaders tomorrow at Home Park but Curle says the prospect of an unwanted replay in Cumbria could affect Plymouth’s approach.

The Blues manager said: “They [Plymouth] will not want a replay, to come to Carlisle on a Tuesday or Wednesday. That could have a massive bearing and make them play slightly differently.

“Them coming here for a replay could have a knock-on for their next game. It would be like jet-lag for them, with two days of travelling, and might have a knock-on effect on their league form.

“That will be in the back of their minds. They are a good counter-attacking team but what if you get two teams prepared to sit in, knowing one team is more than happy to take the replay and one isn’t? They will want the game settled this weekend.”

United are without the ineligible Hallam Hope and the suspended Luke Joyce, while Curle will decide this morning whether Jabo Ibehre and Angelo Balanta are ready to return.

Troy Archibald-Henville could also rejoin the travelling party after missing last weekend’s win against Yeovil.

Curle added: “We will treat Plymouth with a lot of respect. They’re flying high in the division, have had a bit of luck that successful teams seem to get, but cup competitions can be slightly different.

“In the league there [in August] we lost 4-1 but in the first 40 minutes we gave them a footballing lesson. They were desperate for half-time. They got a goal that changed their team-talk and we then gave them a couple of gifts.”

It is another mammoth 780-mile round trip for United’s fans, many of whom will board coaches at 5.30am tomorrow, while Curle added: “It’s going to be a camel ride but we are prepared mentally and physically for the journeys ahead.”

Plymouth boss Derek Adams is likely to be without injured striker Reuben Reid.

If Carlisle get a result at Home Park they will be in the second round draw at 7pm on Monday night. Victory would earn the Blues £18,000 in prize money.

United’s manager said an unnamed member of his squad had turned down the chance of a loan move to a National League club. “It’s a player who needs games but he didn’t feel it was the right move for him,” Curle said.

Curle also praised United’s youth team following Wednesday’s 3-2 extra-time FA Youth Cup win against Tranmere, which booked a second round game at home to Doncaster.

“I was very pleased to see a very competitive youth team who showed good character, faced disappointment, took it as a challenge and came out worthy winners,” Curle said.
