Jimmy Calderwood believes holding home advantage in their final UEFA Cup group game has given Aberdeen a massive boost as they try to reach the last 32 of the competition.
FC Copenhagen visit the 'Granite City' on Thursday night. needing just a draw to advance from Group B but, despite being bottom of the table, the Dons know victory will take them into the knockout stages.
Pittodrie is sold out for the game and will be packed with Aberdeen fans, with Copenhagen selling only 300 tickets.
That is in stark contrast to the 33,000 who filled the Danish side's Parken Stadium and watched Copenhagen's defeat to Atletico Madrid earlier this month.
Dons boss Calderwood attended that match and thinks Copenhagen will miss their passionate home support on Thursday night.
He said: 'I was in Copenhagen for their game against Madrid and the crowd was fabulous in a wonderful stadium on a very cold night.
'They backed their team to the hilt so I am sure their players will miss that.'
Calderwood praised the Aberdeen faithful, who have turned out to watch their team in the two European home games so far, against Dnipro and Lokomotiv Moscow.
The Dons boss conceded that in Clydesdale Bank Premier League games at Pittodrie, the atmosphere can become prickly if the home team are not at their best.
But Calderwood is certain Dons fans will be at their most vociferous for the crunch tie with Copenhagen.
He said: 'Aberdeen is special on European nights.
'The fans can be a little bit hard on the players in league games, but on the European nights we've had at Pittodrie, they've been wonderful.
'Normally, in a league match, you may get away with your first bad touch, but the second one you won't.
'You can take that to five in a European game though - as long as it's not costly.'
