Pedantic mode on: Tesco H/O is based in Cheshunt, not Welyn Garden City. Pedantic mode off.
To have Tesco as main club sponsor would undeniably be of great benefit to the club, not least in assisting to bring in other high profile partnership deals.
However I doubt the directors would of been hopeful of securing a £25k+ main shirt sponsorship by dealing soley with the community team at the Leigh store.
Perhaps a request was made/re-directed centrally through the correct channels and subsequently turned down ? We do not know.
Let's be honest, Tesco will be first on the list of most sports clubs (at all levels of sport) along with various charities nationally seeking sponsorship. They will receive numerous such requests annually. They can not support each one everytime but that's not to say we do not try again in the future.
