Carlisle manager Greg Abbott has revealed he is "chasing" down four transfer targets ahead of the new season.
He told BBC Radio Cumbria: "I think we have got four players that we think would make a big impact on the squad and we are chasing them down.
"One is a real long shot but he is one that I am going to chase and until he tells me he is going to do something different I am going to chase.
"The others are all impact players that would definitely add something to our squad that is probably better than what we have got.
"But, it is a bit of a patience game, we have got to wait until they become available and then try to strike.
"But, I would feel that out of that four certainly two of them might become available, but maybe not for a week or ten days just yet."
