Skysports.com understands Carlisle United have agreed a deal to bring in Manchester United youngster James Chester on loan.
Carlisle boss Greg Abbott has been busy trying to improve his squad ahead of next weekend's big kick-off and signed trialist Francois Zoko earlier in the week.
The League One club have confirmed a signing from the Premier League is imminent and it is understood that defender Chester is the mystery target.
Managing director John Nixon told the club's official website: "We're delighted to be able to report that it looks like all of the hard work has paid off.
"We will definitely have one and possibly even two players from a Premier League team in our squad tomorrow. It's good news for us as we continue to work towards the first game of the season next weekend."
Abbott added: "We've spent a lot of time on the phone with one of the top Premier League clubs and we are delighted with how it has gone.
"Out of courtesy we won't name names just yet, as there is still a little bit of work to do, but we should be in a position to say more ahead of kick off tomorrow."
Chester has made just one substitute's appearance for United and has previously had loan spells at Peterborough United and Plymouth Argyle.
