Crystal Palace youngster Sean Scannell is on the verge of signing a new long-term contract at Selhurst Park.
The 17-year-old forward had a huge impact on Palace's run to the play-offs last season after breaking into the first team, and earned himself a call-up to the Republic of Ireland squad.
His performances have put a number of Premier League clubs on alert, with Aston Villa credited with an interest in his services.
The Eagles are keen to secure Scannell's future having lost talented teenager John Bostock to Tottenham already this summer.
"We are finalising a deal with Sean to commit himself for the next three or four years," Eagles boss Neil Warnock told the South London Press.
"We can't expect too much of him or the other young lads who came into the side last year, but Sean's trained hard in pre-season and he helped turn last season around.
"I expect him to have a big contribution and to get in the Republic squad was a tremendous boost for him."
ExitMeanwhile, Millwall have completed the signing of Tony Craig from Crystal Palace for an undisclosed fee.
The 23-year-old defender spent the latter part of last season on loan at The Den, having joined Palace from the Lions the previous summer, and has now agreed a three-year deal to return to his boyhood club.
"I was very impressed with Tony during his loan spell last season and I think he will be a good asset for us," Lions boss Kenny Jackett told the club's official website.
"He will have benefited from the experience of being away from here for a year but he's still a good age and he's fully focused on helping us win promotion to the Championship. I'm very much looking forward to working with him again."
