Glasgow council said the "damage, disruption and antisocial behaviour" of yesterday's Celtic celebration was "unacceptable".
The local authority hit out after thousands took to Trongate to mark the club's Scottish Premiership title win.
Fans were pictured climbing on traffic lights, bus stops and structures.
Flares were lit and the street was littered with rubbish after the crowd left in the evening.
Officials commended the "exceptional clean-up effort" which took place overnight.

A spokesperson said: “As crowds began to disperse last night, they left a substantial amount of litter, debris and broken glass in a wide area around Glasgow Cross.
“After an exceptional clean-up effort by our teams overnight, the area is now clear – including the course for the Cancer Research UK Race for Life, which is taking place this morning.
“There has been damage to infrastructure such as bus stops and traffic signals, but we do not yet know the full extent of what repairs will be necessary.
“This kind of damage, disruption and antisocial behaviour remains unacceptable. It should be possible to celebrate and show a basic level of consideration for others in the city at the same time.”
