Chelsea are offering free tickets to their Champions League clash with RacingGenk.

The Daily Mail says Chelsea fans planning to boycott the game against Genk fear their protest has been wrecked by the club giving away free tickets.

Many long-standing supporters and season-ticket holders have pledged to join the 'Boycott Genk' campaign to oppose the price rise from £30 to £40 for this season's Champions League group games.

Four years ago, a similar boycott produced an attendance of fewer than 25,000 for a Champions League fixture at home to Rosenborg.
