Stevie McLaren, Clydebank FC's commercial director, said: "I would like to thank Clyde Shopping Centre for their support over the last nine years."
"But when the opportunity came up to join forces with the Co-op it was fantastic."
"The Co-op has been here for 125 years and this is a great sponsorship for us and the community as a whole."
Robert Sider, Clydebank Co-op chief executive, added:
"Myself, the executives and the board are absolutely thrilled to get the opportunity to take on the sponsorship of Clydebank Football Club.
"Over the last couple of years we have been very active within the community and this is not purely a commercial venture for us because we feel it is important that the club gets as much support as possible."
