Celtic's Champions League clash in the San Siro could be staged in front of a full house, according to Milan's sports and security chief.
UEFA this week confirmed the second leg of the Scottish champions' last-16 tie against AC Milan would take place at the San Siro but in front of a limited capacity.
Inter Milan's game with Valencia on Wednesday will take place in front of 36,000 fans as the stadium is brought up to scratch following the introduction of safety rules sparked by the death of a policeman amid the violence before a Catania v Palermo game.
Hoops fans allocated one of the 4,850 official tickets are guaranteed a seat but around double that number are expected to travel for the March 7 game.
Celtic have warned those without tickets to stay away but those fans will fancy their chances of buying a ticket in Italy if Milan are able to open all of the stadium.
Security boss Giovanni Terzi told the Sunday Mail: 'We are in the process of installing more turnstiles at the San Siro.
'There will be 40 for Inter's game against Valencia this week but, by the time Celtic come, there should be 60, which would let in 80,000 fans.'
