The meeting between Bayern Munich and Juventus, two former winners with designs on reclaiming the crown, is the stand-out fixture on Matchday 2 of the UEFA Champions League's group phase. Elsewhere, competition newcomers Debrecen, Rubin Kazan, Unirea Urziceni, AZ and APOEL Nicosia all make their home debuts with the hope of pulling off wins against more experienced opposition.
Match of the day
Bayern Munich-Juventus, Group A, Munich, 20:45
Although these two giants of the continental game have made 14 final appearances between them, it has been six long seasons since either made it that far. Despite their faltering domestic form, Bayern earned a 3-0 win at Maccabi Haifa in their group opener, while Juve had to make do with a draw at home to Bordeaux, putting them under pressure to take something from their trip to Bavaria.
The two have been drawn together twice before in the group phase, with the Italians winning three times and losing once. Yet, having gone unbeaten in their last five home matches in the competition, the Germans will be confident of improving that record.
The other matches
Thanks to that point in Turin, Bordeaux have given themselves a real chance of making an impact in Group A and should swell their points tally at home to Maccabi Haifa, bottom of the section after falling at home to Bayern two weeks ago.
Manchester United seem to have got over the departure of Cristiano Ronaldo already. Now top of the Premier League, Sir Alex Ferguson's side have also made a strong start in Group B, kicking off with a 1-0 win at Besiktas. German champions Wolfsburg were just as impressive in defeating CSKA Moscow 3-1 but face a stiff test at Old Trafford on Wednesday, where the Manchester giants are unbeaten in 28 matches.
In Group C, Real Madrid and AC Milan both won their first games and have the chance to consolidate their positions at home to Marseille and FC Zurich respectively. While the free-scoring Real struck five in Switzerland a fortnight ago, and have already hit the back of the net 16 times in five Liga outings, the ageing Italians have been struggling. Nevertheless, as they showed in Marseille, their vast experience on the big stage makes them formidable opponents.
Rocked by a shock 3-1 league defeat by Wigan Athletic on Saturday and hampered by the continued absence of goal-getter Didier Drogba through suspension, Chelsea should still have more than enough firepower to overcome Group D opponents APOEL in Nicosia. After winning their three home ties in the qualifying rounds and holding Atletico Madrid to a goalless draw in Spain, the Cypriots should not be lacking in confidence, though. Porto welcome Atletico in the other game in the section, having boosted their morale with a 1-0 defeat of old foes Sporting at the weekend, raising their hopes of beating the Spaniards for the first time in the competition and of claiming second place.
In Group E, Liverpool visit Fiorentina tonight hoping to defend their proud record of never having lost in Italy in Europe's premier club competition. Almost as impressively, La Viola have yet to concede a goal against English opposition in the tournament but will be without the suspended striker Alberto Gilardino. Narrow victors over Fiorentina in their first game, Lyon face a testing trip to Hungary to take on new boys Debrecen.
Russian champions Rubin Kazan continue their tough apprenticeship in Group F with a trip to Inter Milan, who have just suffered their first reverse of the Serie A season. And in the section's other match, Barcelona entertain Andriy Shevchenko and his Dinamo Kiev team-mates with the sole objective of moving to the top of the group.
Two years on from their UEFA Cup triumph in Glasgow, Group G favourites Sevilla return to the Scottish city to take on a Rangers side looking for their first home win against Spanish opponents in 20 years. The Scots kicked off with a 1-1 draw at Stuttgart, who will be out to make up for that disappointing start when they travel to Romania to face Unirea Urziceni.
Finally, the winners of the Group H showdown between Arsenal and Olympiacos will take a major stride towards the next round. If history is anything to go by, Arsene Wenger's men should have little trouble in disposing of their opponents. The Piraeus side have lost on their last eight visits to England, conceding 27 goals in that time and scoring only seven. Over in Holland, meanwhile, AZ play host to Standard Liege of Belgium.
Player to watch
Manchester United's Welsh star Ryan Giggs has scored in 13 different Champions League campaigns. The only player to eclipse him in that respect is the equally evergreen Raul of Real Madrid, who struck his 65th goal in 14 campaigns against FC Zurich on Matchday 1.
30 years and 332 days - The average age of the APOEL Nicosia squad, the oldest in this season's Champions League and the sixth-oldest in the history of the competition.
What they said
"Iker Casillas is an amazing goalkeeper for both club and country. He has the lot in terms of ability and he's experienced and very calm too. To my mind he's the best keeper in the world," Marseille goalkeeper Steve Mandanda.
