Danny Mills has hailed Rangers target John Lundstram as an “exceptional” player who would be a shrewd signing for top clubs after he rejected a new Sheffield United contract.

Speaking exclusively to Football Insider correspondent Dylan Childs, the former England defender revealed he is a big admirer of the 26-year-old midfielder.

United boss Chris Wilder revealed at his media conference last week that Lundstram will not be signing a new contract with the club ahead of his deal expiring next summer and admitted he could be sold in January.

The proven Premier League performer’s availability has already alerted Rangers, a recruitment source has told Football Insider, while there is also interest from Crystal Palace and Burnley.

Mills is in no doubt about the calibre of Lundstram after he adapted seamlessly to the English top flight last season, which was United’s best-ever Premier League campaign.

“Lundstram has made it clear that he does not want to sign a new contract at Sheffield United and he is probably thinking that this is his one big move, big opportunity,” Mills told Football Insider

“Now it is a case of what Sheffield United do. Do they cash in in January? Take that money and rebuild or allow him to let his contract run out?

“I think a lot of mid-table sides will be looking at him. He was exceptional last season but you can see already that Sheffield United are starting to struggle.

“He is a quality player with lots of decent attributes so there is no reason why he would not be a welcome addition to any team outside the top eight as well as the big two in Scotland.”

In other news, the door has opened for Rangers to sign £4m-valued star loved by Ross Wilson on pre-contract ahead of January window.
