Sports Mole has teamed up with Heineken to offer you the chance to win an official Champions League football signed by Rio Ferdinand.
As part of Heineken's #ChampionTheMatch campaign, Queens Park Rangers centre-back Ferdinand answered questions during last week's last-16 tie between Real Madrid and Schalke.
Tonight, former Liverpool and Real Madrid goalkeeper Jerzy Dudek is answering questions on Twitter during Barcelona vs. Manchester City and to enter the competition for the signed ball you need to send in a question for the Pole.
To send Dudek a question, all you have to do is write a tweet to @SportsMole and @Heineken that includes the hashtag #ChampionTheMatch, and it could be answered by the man himself.
If you don't have Twitter, but still want to get involved, send your question in an email with the subject line 'Jerzy Dudek #ChampionTheMatch' to mailbag@sportsmole.com and, if we like it, we'll ask it for you.
This competition is for UK residents only. You must be 18 or over to enter.
