Soaring ticket prices are set to turn Chelsea fans away from Champions League matches at Stamford Bridge.
Last night, 34,000 supporters turned up to watch the Blues beat Bayer Leverkusen 2-0 which was the Southwest London clubs worst Champions League crowd since 2007.
A rise of 33% on ticket prices caused the low attendance and supporters groups are now looking to boycott further matches in the European competition.
"Not only am I boycotting Genk, I am also boycotting Leverkusen and Valencia," Chelsea Supporters' Group vice-chairman Michelle Shaw wrote on her organisation's website.
"My choice, I know, but I made the decision as soon as the ticket prices were announced.
"Why? Because I don't want to wake up one May and find I can't afford my season ticket any more.
"The only way to send a message to the club is by a low attendance at the Genk game."
Chelsea reduced their Champions League prices by almost half after fans did not show up for a group stage match against Rosenborg in 2007 as tickets were worth £48.
But prices went back up to £40 this season as the club also increased ticket prices for other competitions for the second straight year.
