40x71 - Match of the Day

Coverage from the Nou Camp of the second leg of Celtic's fourth-round tie against Barcelona. Martin O'Neill 's side were runners-up in the competition last year, beating the likes of Liverpool, Celta Vigo and Stuttgart, and will be hoping to go one better this time around. But first they have to make it past Barcelona to the quarter-finals, and on home soil the Spanish side will be no pushover.
