Celtic manager Neil Lennon is particularly keen to avoid being drawn against Manchester United or Borussia Dortmund in the knockout phase of the Champions League.
The draw for the last 16 will take place on Thursday at 10.30 GMT, with Celtic eagerly awaiting their fate after they finished as runners-up in Group G.
Lennon is expecting a tough test regardless of the opponents but has earmarked Sir Alex Ferguson's United and Bungesliga champions Dortmund as ties to avoid.
"Every one of them's a quality side," Lennon told BBC Radio 5 live.
"I'd like to avoid maybe Manchester United and Dortmund. But, whoever we get, we'll take - we're really looking forward to it and excited about it."
