Dundee have completed the signings of former Rotherham United full-back David Worrell and David O'Brien, the winger having left Stirling Albion. Worrell and O'Brien were out of contract and are the first of six summer signings planned by Dundee. O'Brien, 23, leaves after helping Stirling win promotion to Division One. First Division Dundee have also confirmed that manager Alex Rae will receive an increased budget for next season. But chairman Bob Brannan has stressed to the Tayside business community that further cash will have to be raised to balance the budget. Chief executive Dave MacKinnon pointed out that the club is considering developing land for housing. Dundee are looking at developing the Dens Park side of their stadium "with a new South Stand as part of the development". MacKinnon has held initial discussions with a building developer.
