A collection of documents belonging to Ipswich Town legendary manager Sir Alf Ramsey has sold for £12,000 more than it was expected to fetch at auction.

The documents, including preparation for the 1966 World Cup final, when Sir Alf was managing England, went under the hammer at Diss Auction Rooms on Thursday morning.

They sold for a price of £13,500 to an unidentified buyer.

The collection went up for auction after the death of Elaine Coupland, a close friend of Sir Alf and his wife, Lady Victoria, who took ownership of the items after the Ramseys had passed away.

Training sessions, medical checks, ground inspections, kit orders and the dividing of prize money are all discussed in the letters. 

It was estimated before the hammer fell that the lot would sell between £1,000 and £1,500.

"Not only that but it comes from the man at the helm of it all, it is completely unique, and also a one-off chance for someone to own a piece of the crowning glory of England’s football history."
