FIFPro say there is an argument to allow the players, three from each club, who all picked up yellow cards in the semi-finals, to be allowed to play. The players' union points out that UEFA will adopt FIFA's policy for Euro 2012 where existing yellow cards are waived after the quarter-finals.
The Chelsea players are Branislav Ivanovic, Ramires and Raul Meireles, with Luiz Gustavo, David Alaba and Holger Badstuber from Bayern.
FIFPro spokesman Simon Barker said: "Anybody committing a serious offence in the semi-final should be awarded a red card and miss the final.
"But the offences that result in a yellow card do not justify the serious punishment of missing the match of your life.
"For example, Alaba slipped over and gets the ball kicked against his hand - it is not right that such a player should miss the Champions League final because of this.
"Some people say that this will give players the licence to kick all and sundry during the semi-final, but that is utter nonsense.
"Any serious offence will result in a red card and that still means exclusion from the final."
