MARK WARBURTON has shut down speculation linking Celtic with QPR youngster Sinclair Armstrong.

The Hoops along with Manchester City and Southampton were linked with the 18-year-old striker in a report by GOAL.

The youngster is also said to be attracting interest from Germany, but Warburton was quick to dismiss the speculation.

“I’d imagine his agent has been extremely busy. He’s 18 and played eight games for Torquay." he joked.

“I’m not being derogatory in any way, I just don’t want to put pressure on a young player’s shoulders too early.

“Rumours of Celtic and Man City? I’d imagine certain agents have been extremely busy.

“When you see all these names (of big clubs) you just know agents are busy at work in the January window.

“It’s absolute nonsense. Let’s give the boy a chance now for the next stage of his career.”
