Burke received rave reviews for his Gareth Bale-type pace and power in Sunday's 5-0 demolition of St Johnstone.
The Scottish attacker grabbed two brilliant assists for Scott Sinclair, who scored a hat-trick.
The 21-year-old, on a half-season loan from West Brom, has been compared to Bale before following big-money moves to Leipzig and the Baggies, but Celtic fans are really seeing why now.
Brown told a press conference, via 90 Minute Cynic: "Pace and power. He's by far the quickest I've played with. It's great to actually see someone create something from nothing."
According to The Scottish Sun, Burke is in line for a recall to the Scotland set-up after a two-year absence, and it would be richly deserved.
Overall, the youngster has managed three goals in seven appearances under Hoops boss Brendan Rodgers so far and it's likely that those numbers will increase over the coming months.
How the Parkhead faithful would love to sign him in the long term, but time will tell whether that's feasible.
