Who could Celtic face in the last 16 of the Champions League plus draw and match dates CELTIC are through to the last 16 of the Champions League, and are the first Scottish side to do so since 2008. With the draw looming, here are the answers to some commonly-posed questions about the tournament, the draw, and the teams that Celtic might end up facing. When is the draw? The draw is taking place on Thursday 20 December, at 10:30am UK time. It's taking place at UEFA's headquarters in Nyon, Switzerland, and will be presided over by UEFA General Secretary Gianni Infantino and UEFA director of competitions Giorgio Marchetti. They'll be ably assisted by former Liverpool and Manchester City midfielder, and Champions League final ambassador, Steve McManaman. How does it work? There are eight seeded teams, who won their groups, and eight unseeded teams who, like Celtic, came second. An unseeded team is drawn, and then a seeded team is drawn to play them. This repeats until every team has an opponent. Sounds simple. Anything else to know about? There are two main rules of the draw - no team can play a team from their own qualifying group, and no two teams from the same country can play each other. For example, when Real Madrid are drawn, they can only be matched against one of a maximum of five teams, because they are disqualified from playing the team from their own country (Barcelona, Malaga) or the team from their qualifying group (Borussia Dortmund). Who could Celtic play? Paris Saint Germain, Schalke, Málaga CF, Borussia Dortmund, Juventus, Bayern Munich, or Manchester United. Celtic have a mixed record against this group of teams, but they have beaten Dortmund and Juventus in the past. Celtic also notched up a win and a draw over Manchester United at Celtic Park in this competition, in 2006 and 2008 respectively. Celtic have never played Schalke or Malaga. Which are the teams to avoid? Manchester United, Juventus and Bayern are all topping their domestic leagues at the moment, and Dortmund went undefeated in their Champions League group which contained Real Madrid, Ajax and Manchester City. Dortmund and City's local rivals Manchester United are the two teams Neil Lennon has said he wants to avoid. And which team might be the softer option? Schalke could be the best bet for Celtic fans, as they've won just two of their last ten games in all competitions, although they were on a six-match winning run immediately prior to that. It sounds like cliche, but there are no bad teams at this stage of the competition. Where and when are the games? Celtic will play the first leg of their tie in Glasgow on either the 12th, 13th, 19th or 20th of February. They'll be on the road for the return leg on the 5th, 6th, 12th or 13th of March. What are Celtic's chances? History won't fill Celtic fans with confidence. In the last three years of Champions League football, only seven of the 24 teams in Celtic's position have qualified for the Champions League quarter-finals. As for the bookies, Scotbet reckon Celtic are a 125/1 outsider to go on and win the competition, with only Galatasary having less of a chance of European glory.
