Celtic's return to Benfica's Stadium of Light, where they became the first British winner, is full of nostalgia after the club invited eight of the surviving Lisbon Lions to the match as part of the 40th anniversary celebrations of that 1966/67 triumph.

Lyon, who have never got past the quarter-finals, are on a run of 15 games unbeaten in all competitions following their 1-0 win over Nancy on Sunday and a draw at home to Dynamo Kiev will earn their spot in the knockout stages from Group E.

Lyon have only failed to win a single game this season, a 1-1 draw at home to Toulouse in their second French league match.

Real Madrid, who lost to Lyon in their first match, have won their two matches since and will qualify should they beat visitors Steaua Bucharest and Kiev fail to beat Lyon.

Sir Alex Ferguson will field his strongest available side as Manchester United look to book their place with a win over FC Copenhagen in Denmark.

Three straight wins have left United at the top of group F and a point would be enough to secure qualification if Celtic can take anything from their trip to Lisbon.

But Ferguson is determined to maintain the momentum of United's flying start to the season against the Danish champions, who paid the price of attempting to take on the Red Devils at their own attacking game when they went down to a 3-0 defeat at Old Trafford on October 17.

The Scot, who will celebrate 20 years in charge of United on November 6, insisted: "One point isn't enough, so we're going to try and win it. We want to keep the form right so I'll be playing my strongest team.

"Copenhagen are a good technical and organised team and their approach play was very good at Old Trafford in the last game. But we played well on the night and could have scored a few more goals.

"I don't expect them to change how they play on Wednesday. They'll continue to play their football and I'm sure their approach play will be very good. But as long as we defend properly, I think we have a good chance."

Should Celtic book their last 16 berth in front of captain Billy McNeil and the eight surviving members of Celtic's 1967 triumph, it would be an emotional night for the Bhoys.

McNeil told uefa.com: "Obviously it's the connection between Lisbon and Celtic which will never be lost, but it's a terrific gesture by the club and one that's greatly appreciated.

"It's the first time the Lions as a group have been asked to go to an away game like this. There have been occasions when a few of us have gone out to games, but to take everybody is fantastic."

McNeil added there was sadness that keeper Ronnie Simpson, midfielder Bobby Murdoch and winger Jimmy Johnstone, who have since died, could not be present.

Celtic have been back to the Stadium of Light just once since, in November 1969 in the second round of the competition, on their way to a final appearance against champions Feyenoord.

Of course Celtic earned a stunning 3-0 win over Benfica two weeks ago but that was at Parkhead in Glasgow.

Arsenal have the chance to put one foot into the knockout stages should they win at home against Group G leaders CSKA Moscow and avenge a defeat by the Russians a fortnight ago though Porto would still be in the running in a three-horse race should they beat bottom club Hamburg in Germany to condemn them to last place.

Out-of-form Hamburg only won their first German league match eight days ago in a 2-1 victory at Bayer Leverkusen.

Six-times champions AC Milan would go through from Group H with a victory at home to Anderlecht should AEK Athens fail to beat Lille in the Greek capital.
