The Sun reported that Tottenham defender Udoji was suspected of leaking the tactics of new coach Thomas Frank.

Frank is transplanting the Brentford-era set piece concept to Tottenham. His coaching team has recruited former Arsenal and Manchester United set piece coach Andreas Georgeson. The training images exposed on social media reveal tactical details. The team Bian Wudorji accidentally exposed the training plan of the day on social media, and the last item of the schedule was marked as "long-distance outbound ball".

14 of Brentford's 66 Premier League goals last season were from set pieces, accounting for 21%, which is second only to six teams including Arsenal. What's even more amazing is the performance on the defensive end, losing only 3 set balls throughout the season, 3 fewer than Manchester City, the second best defense. Former set-piece coach Keith Andrews has now taken over as Frank to become the Brentford coach, and the system he has created has made an indelible contribution.

Frank also pioneered the opening blitz tactic when he coached Brentford. In three consecutive games against Manchester City, Tottenham and West Ham in September last year, the team scored within one minute of the opening game. Now with the exposure of long-distance extra-boundary training, Tottenham may present more diverse offensive routines in the new season.
