Celtic's Champions League game kickoff against Barcelona on Tuesday was delayed for 30 minutes because of a turnstile failure at Celtic Park that locked out hundreds of fans. That's almost as long as the 90,000 fans in Calcutta's Salt Lake Stadium had to wait last week for the floodlights to go back on after a rat trapped in an electric substation ignited a small fire. ''These kind of things happen. It didn't affect us,'' said Japan coach Zico, whose team beat India, 4-0.
