The same year, Arsenal became embroiled in a scandal; footballers' pay at the time was limited by a maximum wage, but an FA inquiry found that Charlie Buchan had secretly received illegal payments from Arsenal as an incentive to sign for the club. Sir Henry Norris was indicted for his part and banned from football, but Chapman escaped punishment, and with the autocratic Norris replaced by the more benign Samuel Hill-Wood, Chapman's power and influence within the club increased, allowing him control over all aspects of the club's business. He persevered in building the team, strengthening his attacking lineup with the signings of David Jack in 1928, and Alex James and Cliff Bastin in 1929. As at his previous clubs, Chapman worked on improving the defence, notably through the signings of Herbie Roberts and Eddie Hapgood at centre half and left back respectively.
