Reports from Thessaloniki suggested that City fans were quick to discover the bars and the cafeterias in the city, causing some disturbances that brought about police's intervention.
The squad had been scheduled to arrive to Thessaloniki airport "Makedonia" for 7 p.m. but a delay held them back for an hour, which also meant a delay in the press conference planned for Monday evening.
City had informed Aris they would not be training in Greece at all on the eve of the match at the Kleanthis Vikelidis Stadium and will only participate in the press conference required by UEFA.
Aris coach Yiannis Michalitsos made it clear this is a challenge for a club like Aris, who will be trying to protect their unbeaten home record in Europe, that has lasted for 42 years, in front of a capacity crowd of 15,000 fans as well as some 1,000 City supporters.
"We both want to maintain our unbeaten home record and to face a challenge such as the match with Manchester City, a club to have acquired Yaya Toure from Barcelona and whose fourth striker is out on loan to Real Madrid," Michalitsos said on Monday. "This is why it's a challenge for us to do our best."
"This certainly is a match of great significance. Fear will not help us beat anyone. This is why we have to do better than usual in this game, as we have done in all our European matches," the Greek coach added.
Michalitsos will be happy to welcome back Greece goalkeeper Michalis Sifakis to his squad for the game that kicks off at 7 p.m. on Tuesday.
