Yes, I had read that, but it says nothing about Moores / Littlewoods funding the club.
Williams enticed Shankly to leave First Division Huddersfield to go to Second Division Liverpool with the carrot of having more money to spend than Huddersfield had ambition to.
Shankly bought 24 players in one Summer to gain promotion.
Liverpool failed to go up.
“Shareholder John Moores felt the club needed to spend more money on players to be successful and encouraged chairman T. V. Williams to do so.”
From Williams, John (2010). Reds: Liverpool Football Club – The Biography.
Shankly signed Ian St John for a club record and the second highest fee paid for any player in Europe that Summer. As well as other signings.
They gained promotion. Signed more players. Then Liverpool won the league title and FA Cup.
They were a languishing Second Division club and without Moores’ funding they would have remained so.
Liverpool then went 6 years without winning anything so went on a spending spree never seen before in English football. They broke their club transfer record a number of times, the record ever spent on a teenager or a record spent on a player in a certain position numerous times... they never looked back.
That’s when Liverpool went on to dominate the next two decades.
