in groups with the purpose of achieving set targets. These would first cycle through athletic exercises, like skipping or squats, before moving on to football-specific functions, such as a heading the ball or chipping it. Five-a-side games, as at all Shankly's earlier clubs, were at the heart of the system and he again insisted on these being as competitive as league matches. One particular routine designed to develop stamina, reflexes and ball skills was the "sweat box" which Shankly described as: "using boards like the walls of a house with players playing the ball off one wall and on to the next; the ball was played against the boards, you controlled it, turned around and took it again". Shankly got the idea from a routine he had seen Tom Finney use at Preston to hone his skills. After experimenting with the routine, he set the players a limit of two minutes per session. The system was geared to Shankly's simple philosophy of "pass and move", which formed the basis of Liverpool's strategy. Shankly insisted on suitable cooling-off periods after training (now called "warming down") before the players took a bath and had a meal. The team changed the studs in their boots to suit all playing conditions. Shankly summarised the entire strategy in terms of attention to detail with nothing left to chance. Liverpool's recovery depended on new players being acquired and, in his autobiography, Shankly recalled the struggles he had with the board to make them realise the club's potential and the need to spend money on good players. He said there were times when he felt like walking out. He found a valuable ally in Eric Sawyer, of the Littlewoods pools organisation, who joined the board not long after Shankly's appointment and shared Shankly's vision of Liverpool as the best club in England. At one board meeting in 1961 when Shankly insisted the club make offers for two players in Scotland, the board's initial response was that they couldn't afford them, but Sawyer stepped in and said: "We can't afford not to buy them". The two Scottish players were centre half Ron Yeats and centre forward Ian St John from Dundee United and Motherwell respectively. With Sawyer's help, Shankly signed them both in the spring of 1961 and challenged the Liverpool board to sack him if they couldn't play. At a press conference when Yeats came to Liverpool,
