Tickets to Man U v Chelsea Apr

Hi all,

Talk about long shots! ..but here goes

A friend of mine will be in London for the Chelsea-ManU match on April 26 at
Stamford Bridge and I was wondering if anyone might have a spare, or advice
about getting tickets, et cetera?

I'm guessing the chances are slim given the game in question - anyway
there's a bottle of Australian shiraz in it plus my eternal gratitude

Thanks All - much obliged
