The as yet untitled track, will feature heavily around team activities during May; the final itself takes place between Arsenal and Liverpool at Cardiff's Millennium Stadium on 12th May.
The pair found time to record the song between prolonged bouts of touring - including a UK tour supporting Feeder and an one-off support slot with Eminem.
"A few months ago we went to pick up one of our DJs for a show and he lives near Dennis Bergkamp," said Blade to xfm. "We suggested it as a joke. Next thing I know, we're in the States and someone calls and asks us if we want to do the Arsenal rap."
"It was a hectic time when we did the track, we were flying up and down the country. I haven't heard the finished product yet, just the bits where I'm rapping and the scratching. I don't know what's going on in the chorus!"
Mark B & Blade are currently big in the world of football-related songstery - Cambridge United have invited them to appear on the pitch prior to their last home game of the season after adopting the remix of Feeder 's 'Ya Don't See The Signs' as their run-out anthem.
