"Emergency services are present at the scene and the fire has now been extinguished.
"The safety of all attending the match tonight is our top priority.
"And as such all events planned for West Stand reception have been cancelled, including the welcome event for new players, and the first team arrival."
Meanwhile, a spokesperson for Greater Manchester Fire and Rescue Service (GMFRS) said: "Just before 6pm this evening (Wednesday 29 January), two fire engines from Blackley and Philips Park fire station were called to reports of a building fire involving an outbuilding on the car park of the football ground on Rowsley Street, Manchester.
"Crews arrived quickly at the scene.
"Firefighters wearing breathing apparatus used two hose reels to extinguish the fire, they are currently dampening down any hotspots and making the area safe.
"Firefighters have been in attendance for around thirty minutes and are still at the scene."
For City, they go into their meeting with Brugge with their destiny in their own hands.
As it stands, they sit in 25th spot - one place below the cut-off for the knockout play-off stage.
But they know that victory will see them progress into the next round.
However, Brugge, who sit two points and five places above City, go into the match in great form with the club on a 20-game unbeaten streak.
