Newport manager Justin Edinburgh admits the loss of Danny Rose to Crystal Palace would be a "major blow".
Rose trained with Championship side Palace this week after the midfielder caught the eye with 10 goals for the Conference side Newport this season.
He was due to return to Spytty Park on Friday ahead of the FA Cup clash with Braintree, but his future is in doubt.
"Of course [losing Rose] will be a major blow but it's about a team rather than an individual," said Edinburgh.
"We would have to continue and recover. But don't get me wrong, 10 goals from midfield is a big return and he would be a big loss.
"Until that happens we will continue to work with Danny.
"Danny's been down at Crystal Palace this week. They've been to see him this season and they like what they've seen.
"And they asked us if they could have him down at Palace to train not as trial. It's a positive. It's good experience for Danny. Something he deserves."
Among his 10 goals, 23-year-old Rose caught the eye with ah hat-trick in the 3-1 win over Kettering last week.
"We don't want to lose him and we are not at the stage of that at this present time," added Edinburgh.
"He's back with us on Friday and I'll have a chat with him. I spoke to him during the week and he's enjoyed it.
"His performances of late have been outstanding, and no doubt there will be more admirers and people asking and enquiring about him."
Edinburgh, who spent 10 years in the top-flight of English football with Tottenham Hotspur, said he would not stand in Rose's way if the right opportunity came along for him to join a Football League club.
"As we speak he will continue to put in the performances for Newport and he is still a Newport player," said Edinburgh.
"And unless we get the right offer that's right for the football club then he will continue to be player at Newport.
"But we have to give these players the opportunity because it's only right that if Championship club come asking. We'll see what develops over the next couple of days."
Any initial move to Palace would have to be on the loan market with the transfer window not opening until 1 January, 2012.
Rose is expected to be in Newport squad for Saturday's home tie with Braintree in the FA Cup final qualifying round as the club look to build on their encouraging 0-0 draw with leaders Wrexham last weekend.
"A lot of positives came out of the Wrexham result. We want to build on that. But it's nothing gained yet," added Edinburgh, an FA Cup winner with Spurs in 1991.
"We want to take Saturday's performance into the FA Cup and continue our progression."
