New Delhi, May 20 -- Spying on its opponents has potentially cost English soccer club Southampton a place in the Premier League and around $270 million.

The team from England's southcoast was expelled Tuesday from the second-tier Championship playoff final after admitting to the unauthorized filming of other clubs' practice sessions.

The playoff final is labelled the world's richest one-off soccer match because a windfall of at least 200 million pounds ($270 million) in future Premier League earnings is on offer for the winning team.
