Pot 1: Barcelona, AC Milan, Real Madrid, Inter Milan, Liverpool, Arsenal, Manchester United, Valencia.
Pot 2: Lyon, Porto, PSV, Bayern Munich, Chelsea, Roma, Celtic, Lille.
Pot 3: Sporting Lisbon, Benfica, Bordeaux, Steaua Bucharest, Weder Bremen, Olympiakos, CSKA Moscow, AEK Athens.
Pot 4: Anderlecht, Dinamo Kiev, Levski Sofia, Shakhtar Donetsk, Galatasaray, Hamburg, Spartak Moscow, FC København.
I think Barcelona will be the team to beat again this year. Despite Chelsea's improvements I think that Barcelona still have a better side.
Lyon and Chelsea are obviously the ones to watch from pot 2 and Weder Bremen, CSKA Moscow and Hamburg have a great chance of getting through if they get a favourable draw.
