Champions' League Match by match

Celta Vigo v Arsenal

Some believe Raddy Antic rather than Giovanni Trapattoni will be facing Arsenal next season from the other end of the Seven Sisters Road. For now Antic is the replacement for Miguel Lotina at Celta, charged with leading the club to a quarter-final in their first Champions' League campaign and away from the bottom six of La Liga. The Brazilian full-back Silvinho, who had questions asked about his passport as well as his defending when at Highbury, will be keen to put one over his former club.

Key man: Thierry Henry (Arsenal).

Bayern Munich v Real Madrid

Whatever the English clubs may say, history insists that the winners of this undoubted tie of the round will go on to take the trophy, as happened when they met in three successive seasons from 2000 to 2002. Bayern, a little fortunate to come through the group stage, and now trailing Werder Bremen in the Bundesliga, will need a good lead to take into the second leg if they are to progress.

Key man: Oliver Kahn (Bayern).

Deportivo La Coruña v Juventus

There will be no excuse for these two not knowing enough about each other after being drawn together for the fourth successive season. Previous meetings have featured a preponderance of draws and Juve, last season's beaten finalists at Old Trafford, would be delighted with another to take back to the Stadio Delle Alpi. They are sufficiently strong to have loaned Edgar Davids to Barcelona and should have enough in their locker to reach another quarter-final.

Key man: Pavel Nedved (Juventus).

Lokomotiv Moscow v Monaco

Concerned about playing during their domestic close-season - a traditional problem for Russian teams in Europe - Lokomotiv have made a number of signings during the transfer window, including the controversial Russian striker Dmitri Sychev from Marseille. Their first French opponents in Europe need not fear a Napoleonic campaign, coach Didier Deschamps rightly pointing out that the draw "could have been worse".

Key man: Dado Prso (Monaco).

Porto v Manchester Utd

A lucky 1-1 draw away to Benfica maintained Porto's unbeaten record in the Portuguese league this season, keeping them on track to retain the title. United, with Louis Saha available alongside Ruud van Nistelrooy, can exploit Jorge Costa's lack of pace in the centre of defence but must contain Deco, the naturalised midfielder who appeared in the second half for Portugal against England. A bonus is that Costinha, whose place he took, is suspended.

Key man: Roy Keane (Man Utd).

Real Sociedad v Lyon

The Basques have been more successful than Celta Vigo in recovering from a bad start to the Spanish season, reaching mid-table and holding off Galatasaray in their Champions' group to qualify. Having won their group, Lyon should not be under-estimated, and are favourites to reach the last eight. Key man: Elber (Lyon).

Sparta Prague v Milan

Theoretically the most one-sided tie of the eight, with the holders strongly fancied to progress. Sparta, with Karel Poborsky still fairly strong, qualified dramatically thanks to Marek Kincl's late goal against Lazio and fought hard for a draw at Stamford Bridge. But Paolo Maldini, Alessandro Nesta and the rest ought to be able to subdue the Czechs in the first leg and finish the job at home. Key man: Andrei Shevchenko (Milan).

Stuttgart v Chelsea

Stuttgart led the Bundesliga early on, conceding three goals in 15 games. Defence is still their strength, although the Brazilian-born Kevin Kuranyi has now emerged as a powerful German international striker. Frank Lampard (pictured) has scored at crucial times this season and an away goal may be the key for Chelsea, whose occasional failure to break down teams at home could otherwise let them down.

Key man: Lampard (Chelsea).
