The Newcastle head coach has been discussing the former England captain.
But the coach was coy on the former England captain's future, despite clearly rating his obvious skills.
Indeed, McClaren says it must be a 'big wrench' for Terry to leave Chelsea but refused to focus on anything beyond facing the defender at Stamford Bridge this weekend.
The Newcastle boss told reporters when asked if he'd like to sign the 35-year-old: "That’s their decision. I know JT well and he’s a great player and servant for Chelsea, he’s Mr Chelsea.
"To leave and not to be given a contract must be a big wrench for him wherever he goes to leave. How far is the summer? A long time, a lot can happen between now and then.
"So we’re not thinking about that. We’re just thinking about John Terry playing for Chelsea and how we can get past him."
It seems like an ambitious question from the journalist - although one worth asking anyway.
Terry has ruled out joining a Premier League club other than Chelsea and it would appear a new contract at Stamford Bridge is not a total impossibility.
Even if Newcastle were interested, then, it would take a seismic shift for anything to actually happen.
The Magpies face Chelsea in west London this weekend.
