In love with football
                   At eleven o’clock this morning, James and Fiona will look deeply into each other’s eyes, exchange rings and become husband and wife. But at this wedding, there will be no church bells or quiet music. This is because they have decided to get married on the huge pitch at Sheffield Wednesday football club.
          The couple’s friends and family will wear blue and white striped football kit. During the ceremony they will be able to join the couple in singing some of the club’s famous football songs.
           James, 28, first met Fiona, 29, at a Sheffield Wednesday match in 2008 when a friend introduced them to one another in the club shop. They’ve been to every game since then except for one match when Fiona was ill.
          ‘I’ve supported Wednesday for over twenty years,’says James. ‘It was a dream come true to fall in love with another fan. We’ve got a lot in common – we occasionally have an argument, but we’ve never argued about our favourite team!’
         ‘We’ve been saving up for two years to pay for the wedding,’ smiles Fiona, ‘and w e ’ve chosen to have our reception in the club restaurant. It’s going to be an unforgettable day for all of us!’
