Here are mini-profiles of the seven teams that Celtic could face when the draw is made on December 20:

MANCHESTER UNITED

Coach: Sir Alex Ferguson.

Star man: Robin van Persie.

Previous best in CL/European Cup: Winners 1968, 1999, 2008.

Chances: Have marched pretty efficiently into the knockout rounds and look to be among the strongest contenders.

Did you know? United's victory in the final in 1968 made them the first English club to win the European Cup.

JUVENTUS

Coach: Antonio Conte.

Star man: Arturo Vidal.

Previous best in CL/European Cup: Winners 1985, 1996.

Chances: Serie A champions snuck into last 16 by winning final group game and will be expected to step it up when European competition resumes in February.

Did you know? Juve's original strip was pink, back in 1897. They adopted their new colours six years later when Turin-based Englishman John Savage acquired a set of black and white vertical striped shirts from a Notts County-supporting friend.

PARIS ST GERMAIN

Coach: Carlo Ancelotti.

Star man: Zlatan Ibrahimovic.

Previous best in CL/European Cup: Semi-final 1995.

Chances: Mega-rich PSG have ambitions to win the Champions League this term and if striker Ibrahimovic can continue his superb form, it might just happen.

Did you know? Paris St Germain were only formed in 1970, as a merger between Paris FC and Stade St Germain.

SCHALKE

Coach: Huub Stevens.

Star man: Klaas Jan Huntelaar.

Previous best in CL/European Cup: Semi-final 2011.

Chances: Unbeaten through their group, with Arsenal certainly knowing they are not a team to be taken lightly.

Did you know? Stevens is in his second spell as Schalke boss having returned in 2011 - in his first stint in charge the team won the 1997 UEFA Cup.

BORUSSIA DORTMUND

Coach: Jurgen Klopp.

Star man: Robert Lewandowski.

Previous best in CL/European Cup: Winners 1997.

Chances: Have very much caught the eye in the group stage and are being tipped as dark horses for the title.

Did you know? Dortmund, under Klopp, have won the Bundesliga for the past two seasons, securing a domestic double in 2011-12 by adding the DFB-Pokal.

BAYERN MUNICH

Coach: Jupp Heynckes

Star man: Franck Ribery.

Previous best in CL/European Cup: Winners 1974, 1975, 1976, 2001.

Chances: Last season's beaten finalists are looking to make amends and have been effective so far.

Did you know? Bayern lost the 2011-12 Champions League final despite it being played at their home ground, being defeated on penalties by Chelsea at the Allianz Arena following a 1-1 draw.

MALAGA

Coach: Manuel Pellegrini.

Star man: Javier Saviola.

Previous best in CL/European Cup: First time in competition.

Chances: Impressive so far in their debut Champions League season, although inexperience may count against them in the knockout rounds.

Did you know? Pellegrini took Villarreal to the semi-finals of the Champions League in 2006, but during his brief period as boss at Real Madrid, could only get Los Blancos to the last 16.
