Heart of Midlothian's Callum Paterson
The right-back - who is on the Hoops' radar (via The Scottish Sun) - is entering the final year of his contract with Robbie Neilson's side, and with little progress being made regarding talks over a new deal, it appears that he could be on his way out.
Robin van Persie
Mark Warburton has previously spoken about his desire to sign a new striker, but a deal for the former Arsenal and Manchester United man would undoubtedly be one of the surprises of the window.
Rangers manager Mark Warburton
However, Warburton has dampened talk that the Netherlands international could be on his way to Ibrox by telling the club's official website that the targets they are after are yet to be linked.
"We have a number of targets, none of which are on Twitter and none of which have been released," he told the club's official website.
Burnley manager Sean Dyche
The 33-year-old was an integral part of the Clarets' squad this season, and Dyche has tipped him to succeed with his new side.
"He did a brilliant job for us, I hope he does a brilliant job for Rangers and I think he will. I wish him well and wish Rangers all the best," he told the Evening Times.
Also, Mark Warburton has confirmed to the club's official website that Jason Holt will miss the side's upcoming friendly with Dyche's Burnley due to injury, but was much more optimistic about Josh Windass.
"Jason Holt is probably four or five days away, Josh Windass will be back training with us this morning [Thursday] so we will have a full squad apart from that," he told the club's official website.
Finally, Leigh Griffiths has been full of praise for Eoghan O'Connell after defender's performances against Leicester in the Champions Cup and Astana in the Champions League, the Evening Times reports.
"He strolled it against the English Champions and the manager had no qualms about throwing him in [against Astana]. You could see why. He was excellent," he told the Evening Times.
