Milan have warned fans not to travel to Reggio Emilia without a ticket for the Scudetto decider against Sassuolo, but some are being sold for €3,000.
The title will go to the Rossoneri if they pick up at least a point on Sunday evening, with the game kicking off at 17.00 UK time (16.00 GMT).
They could even afford to lose and still be crowned champions of Italy as long as Inter do not beat Sampdoria at San Siro in the match being played simultaneously.
Naturally, all the tickets for Sassuolo-Milan sold out in under an hour, though some will be released for the Tribuna Sud to Sassuolo season ticket holders from Friday night.
La Gazzetta dello Sport reported the online queue for tickets on the site had reached 100,000 at one stage.
The Mapei Stadium is only open for 21,525 seats at the moment and Milan sent out a warning today urging anyone without a ticket to stay clear of the arena in Reggio Emilia to avoid crowd trouble.
Meanwhile, some people are already putting tickets for the match on sale via specialist sites for €3,000.
Come richiesto della Questura di Reggio Emilia, vogliamo ricordare ai tifosi sprovvisti di biglietto per #SassuoloMilan di non mettersi in viaggio e di non presentarsi al Mapei Stadium senza titolo d’accesso ⚠️
