Blackburn boss Steve Kean has warned Sir Alex Ferguson off making a move for Rovers defender Grant Hanley.
Hanley is thought to have impressed Manchester United manager Ferguson during his side's 2-0 win over Rovers at Ewood Park on Monday night.
The 20-year-old has established himself as a regular in Kean's side this term, forming a solid central defensive partnership with Scott Dann.
Kean revealed Ferguson spoke highly of Hanley after Monday's game, but he has told the Old Trafford supremo not to make a move for the young Scot.
"He was very complimentary about Grant," Kean told The Sun.
"He thinks he's good enough to play for Scotland for the next 10 to 15 years, and I agree.
"I hope Fergie's not going to be putting a bid in. I said that to him.
"I told him leave it a bit longer because Grant is only just starting with us."
