Keith Curle has asked Carlisle United fans to "trust" him as he continues his efforts to make a transfer window breakthrough.

The Blues have a week left to add to their squad before the January deadline.

And while Curle has so far been thwarted in his attempts to make signings, he said people should have faith in his recruitment methods.

"They've got to trust me, and trust the process that we've put in place," said the Carlisle boss.

United have been priced out of some targets but are understood to be chasing fresh names, especially in attacking positions.

Discussions with clubs and agents have been held but Curle insisted the situation can constantly change.

"We are looking at the Premier League, Championship, players from League One not getting games, and every day there is a change within the players available," he said.

"As soon as a player becomes available that has the right skill sets, with the contacts we have got we make our pitch.

"Sometimes, unfortunately, we do get used as a bargaining tool - that’s the nature of the window.

"Some players don't answer their phone, or tell you to ring their agent. They've got the power because they are getting options."

Curle also said he expected to find out exactly how Carlisle's recent FA Cup run would boost his spending power.

The prospect of players leaving United before next Wednesday's cut-off remains, meanwhile, with Crewe still keen on a deal for striker Shaun Miller.

Their need for a new frontman has increased, too, with the news that experienced pair Chris Dagnall and Chris Porter have both been ruled out with injury for more than a month.

Manager David Artell today admitted an experienced striker is top of his wanted list.

“We are still active and we are still looking," he told the Crewe website. "We will be watching players again this week and doing the work. We will have to see what comes up and what develops.

“I said ahead of the window opening that we will have more of an ideal of what we will need in mid-January. The injuries to Chris Porter and Chris Dagnall [have] altered our thinking.

"When you lose your captain and leading scorer for a number of weeks, it is important that you do all you can to bring another one in, preferably one with experience.”

United, meanwhile, have been thanked by Stevenage captain Ronnie Henry for presenting him with an engraved clock on Saturday to commemorate his club record 469 appearances.
