Both Celtic and Inter Milan head into Friday morning's (AEDT) UEFA Europa League ties knowing victories on home soil will see them advance to the last 32.
The two sides contested the 1967 European Cup final, but these days they must contend themselves with European football's secondary club competition for a chance of continental glory.
Celtic was dumped out of the UEFA Champions League at the play-off stage by Maribor, but has mounted a solid group-phase campaign and currently stands on the brink of qualification for the second round.
Ronny Deila's side faces Group D leader Red Bull Salzburg - which has already qualified - at Celtic Park, where a win will see it leapfrog its opponent and secure its own progress.
"Salzburg are a very good team so it will be a very big game at home, and hopefully we can get as many people in the stadium as we can," said Celtic defender Jason Denayer.
"It would be great for it to be full. It makes a difference to the other team as well as when you have that kind of atmosphere in the ground, it can be difficult to play well."
The other game in the group sees Dinamo Zagreb travel to Astra, which is already out.
In Group F, Inter tops the table with eight points from its four matches, while the other three sides are all locked on four apiece, and Juan Jesus wants to finish the job in order to avoid any unnecessary nerves on matchday six.
"Thursday, it will be a tough match, we have to win so we are more relaxed in the pool," he said.
Victory against Dnipro at San Siro will see Roberto Mancini's side qualify as group winner, regardless of the result between St Etienne and Qarabag in France.
Dinamo Moscow is one of just two sides to boast a 100 per cent record after four games, with the Russian outfit looking to extend its winning streak at home to Panathinaikos in Group E.
A win or a draw for PSV at Estoril will see Phillip Cocu's men join Moscow in the last 32.
The other side with a perfect record is Legia Warsaw, which travels to Lokeren in Group L. In the other game, a win for Trabzonspor at home to Metalist will assure the Turkish side of a safe passage.
Fiorentina is already through from Group K and Vincenzo Montella's side visits Guingamp, which will qualify if it betters the result of PAOK at Dinamo Minsk.
Tottenham Hotspur boasts the tournament's joint top scorer in Harry Kane, who has five goals to his name, and Mauricio Pochettino will hope the 21-year-old can find the target again as it goes in search of the win it needs to progress at home to Partizan.
Elsewhere in Group C, Besiktas visits Asteras Tripolis, while in Group J, AaB hosts Steaua Bucharest and Dynamo Kiev welcomes Rio Ave.
In Group H, victory for Everton at Wolfsburg will see it qualify as group winner, while Lille and Krasnodar will vie to keep themselves in contention when they meet in Russia.
The top two in Group G clash when reigning champion Sevilla visits Feyenoord, while Rijeka takes on Standard Liege. In Group I, Sparta Prague takes on Napoli and will secure qualification if it betters Young Boys's result at Slovan Bratislava.
Borussia Monchengladbach of Group A takes on Villarreal in Spain, with Zurich hosting Apollon and in Group B Torino hosts Club Brugge and Copenhagen visits HJK.
